How to display error message under right element in the UI

I have these two view model properties that has these validation attributes.

[CardTypeValidation(ErrorMessage = "Card type is mandatory")]
public CCardType CardType { get; set; }

[CardNumberValidation("CardType", ErrorMessage = "Card type is not a right match for the card number provided")]
public string CardNumber { get; set; }

Now my problem is all validation works fine but the error message "Card type is not a right match for the card number provided" is displayed underneath the Card number textbox. (Which is right below the Card Type dropdown).

My tester is after that the message should be displayed under the Card Type dropdown.

If I put this attribute on the Card Type, then it has some wierd exception and not proper validation either. So its just the message instead of getting displayed under the card number, it should display under the card type. How to do that?

Razor MVC 3 Ajax returns 404

I'm trying to do a basic autocomplete via jquery AJAX, using Razor MVC 3 and Visual Studio 2012 (all of which I had never used before) My code is as follows


$(document).ready(function () {        
    $("#city").keyup(function () {
        var input = $(this).val();

function getCities(input) {
    var serviceURL = $("#autocompleteURL").val();    
    var url =
            type: "POST",
            url: serviceURL,
            data: {
                'guess': input
            success: function (data) {

Since i learned that it's not possible to use Razor syntax in a JS file, I'm getting the value from the view via a hidden input, like:

<input type="hidden" id="autocompleteURL" value="@Url.Action("AutoCompleteCity", "Controllers/SearchController")" />


 public class SearchController: Controller
       public ActionResult AutoCompleteCity(string guess)
            //database stuff here

I don't know if I'm missing something else. Any help will be greatly appreciated. Thanks!

Issues in implementing Windsor Castle at app config level

I have written a dummy program that implements Windsor castle below.But my problem is that i want to write its components in my WEB CONFIG but i don't able to know where to write what..can any one helps me in correcting that

Please correct me writing is App.config level of behaviour i.e to make it configurable??? Dummy Programm:

namespace NnjectFramework

    class Program
#region  windsor castle
        interface IFoo
            void test();
            void test2();
        public class Foo: IFoo
            private readonly string _arg1;
            private readonly string _arg2;

            public Foo(string arg1, string arg2)
                _arg1 = arg1;
                _arg2 = arg2;

            public void test()
                Console.WriteLine("Success method 1");
            public void test2()
                Console.WriteLine("Success method 2");
        class Bar
            private Foo bar;

            public Bar(Foo bar)
       = bar;
        static void Main(string[] args)

            IWindsorContainer container = new WindsorContainer();

            IFoo foo = container.Resolve<Foo>("AFooNamedFoo", new { arg1 = "hello", arg2 = "world" });




What i have tried in App.config:

        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />

    <component id="uniqueId"
    service="Acme.Crm.Services.INotificationService, Acme.Crm"
    type="Acme.Crm.Services.EmailNotificationService, Acme.Crm"
    customLifestyleType="type that implements ILifestyleManager"
    componentActivatorType="type that implements IComponentActivator"

Many to many value null

Well im trying to do a many to many relationship with my Desafio(challenge) and my Tag model, a challenge can have many tags and a tag can be related to many challenges, i already placed the tags on the view, the problem is when i submit the form, it says that the value is null on this line:

var DesafioTag = new HashSet<int>(
         desafio.Tags.Select(a => a.Id));

i will show how i did:

my models


 public class Tag
    public int Id { get; set; }
    public string NomeTag { get; set; }
    public string cor { get; set; }
    public virtual ICollection<ApplicationUser> Users { get; set; }
    public virtual ICollection<Desafio> Desafios { get; set; }


 public class Desafio
    public int DesafioId { get; set; }

    public string TipoTrabalho { get; set; }

    public virtual ApplicationUser User { get; set; }

    public string ApplicationUserId { get; set; }

    public string Descricao { get; set; }
    public int TipoAvaliacaoId { get; set; }
    public virtual TipoAvaliacao TipoAvaliacao { get; set; }       
    public decimal valor { get; set; }
    public int Visualizacoes { get; set; }
    public DateTime DataCriacao { get; set; }
    public decimal lat { get; set; }
    public decimal lon { get; set; }
    public int IdSolucaoVencedora { get; set; }
    public virtual ICollection<Tag> Tags { get; set; }


then i have 2 viewmodels to display the data in the view


public class DesafioCreate
    public string Desafio { get; set; }
    public string Descricao { get; set; }
    public decimal ValorMonetario { get; set; }
    public decimal lat { get; set; }
    public decimal lon { get; set; }
    public ICollection<TagDesafio> TagDesafio { get; set; }

 public class TagDesafio
    public int TagId { get; set; }
    public string Nome { get; set; }
    public bool Seleccionado { get; set; }

i already did something with many to many relationships to edit, and i did it, but in a create method it doesnt work, i feel that has something to do with my challenge, cause im trying to associate tags with a challenge that doesnt exist, but i dont know if the cause is that, here is the post code that i think is the main problem here

    public ActionResult Create(DesafioCreate model, string[] selectedTag,HttpPostedFileBase file)
        TipoAvaliacao TipoAvaliacao = db.TiposAvaliacao.Where(i => i.TipoAvaliacaoId == 1).FirstOrDefault();

        if (ModelState.IsValid)
            Desafio desafio = new Desafio();
            desafio.lon = model.lon;
            desafio.TipoTrabalho = model.Desafio;
            desafio.Descricao = model.Descricao;
            desafio.DataCriacao = DateTime.Now;
            desafio.TipoAvaliacao = TipoAvaliacao;
            desafio.valor = 22;
            desafio.Visualizacoes = 34;
            desafio.ApplicationUserId = User.Identity.GetUserId();

            var fileName = Path.GetFileName(file.FileName);
                    var path = Path.Combine(Server.MapPath("~/Anexos"), fileName);
                    var anexo = new Anexo();
                    anexo.Caminho = path;
                    anexo.NomeFicheiro = fileName;
                    anexo.DesafioId = desafio.DesafioId;


            atualizarTagsDesafio(desafio, selectedTag);
            return RedirectToAction("Index");
        return View(model);

    private void atualizarTagsDesafio(Desafio desafio,

string[] selectedTag)
            if (selectedTag == null)
                desafio.Tags = new List<Tag>();
            var selectedAutoresHS = new HashSet<string>(selectedTag);
            var DesafioTag = new HashSet<int>( // line that cause the error
             desafio.Tags.Select(a => a.Id));  // line that cause the error
            var Tags = db.Tags;
            foreach (var tag in Tags)
                if (selectedAutoresHS.Contains(tag.Id.ToString()))
                    if (!DesafioTag.Contains(tag.Id))
                else {

                    if (DesafioTag.Contains(tag.Id))

if soemeone can give me a hand, im a beginner doing this relationships, and i cant find the problem.

Ps: Sorry for my bad english

I am trying to add pagination to my website and followed this guide:

My Controller looks like this:

using PagedList;
using PagedList.Mvc;

public ActionResult Content(int? page)
   int currentPageIndex = page.HasValue ? page.Value - 1 : 0;
   Other code here...
   return View(model.ToPagedList(currentPageIndex, 10));

And my View looks like this:

@using PagedList;
@using PagedList.Mvc;
@model IPagedList<Prj.Models.ContentModels>

@foreach (var content in Model)
   Table code here...
<div class="pager">
   @Html.Pager(Model.PageSize, Model.PageNumber, Model.TotalItemCount)

The problem is however that the @Html.Pager part doesn't seem to work. I get the following error:

'HtmlHelper<IPager<Models>>' does not contain a defintion for 'Pager' and no extension method 'Pager' accepts a first argument of type 'HtmlHelper<IPageList<Models>>' could be found (are you missing a using directive or an assembly reference?)

I have installed both PageList and PageList.Mvc via NuGet.

Why does Html.CheckBoxFor output a 'false' as the value where a Html.HiddenFor outputs a 'False' (lower vs proper case)?

I'm not sure if it is intended behavior or not but when I use a @Html.CheckBoxFor(x => x.CheckBox1) it will output two input fields (one of which is false and one is true because html doesn't post back false checkboxes). But the actual html rendered is:

<input id="CheckBox1" name="CheckBox1" type="checkbox" value="true"> <input name="CheckBox1" type="hidden" value="false">

But when I use a @Html.HiddenFor(x => x.CheckBox2) the output is:

<input id="CheckBox2" name="CheckBox2" type="hidden" value="True">

Note the 'true' and the 'True'. When the out of the box jquery.validate.js tries to use the equalTo function it will never be equal to each other because 'true' !== 'True'.

To get around this I can modify the equalTo method to ignore case when comparing checkbox values but I was just curious if this is a bug with the MVC framework or this was intended behavior?

Here is a fiddle reproducing the issue (view source on the output to view the html):

Edit 1: I have found in the CheckBoxFor source that it is passing a lower case 'true' when building the Checkbox. The question still remains, why lower case instead of proper case. Line 96 of the source.

One to Many with Circular Relationship

I'm trying to build a structure that has many domains and menus. All Menus are related to a domain with DomainID, So each domain can manage owns.

Also, domain owners can select where to show to menu, it may be on Heade or on Footer areas.

Here is my models

public class Domain
        public int DomainID { get; set; }
        public string Name { get; set; }
        public string Template { get; set; }
        public string BookingType { get; set; }

        public int? HeaderMenuID { get; set; }
        public int? FooterMenuID { get; set; }

        public virtual Menu HeaderMenu {get;set;}
        public virtual Menu FooterMenu { get; set; }

        public virtual List<DomainTranslation> DomainTranslations { get; set; }
        public virtual List<Language> Languages { get; set; }
        public virtual List<User> Users { get; set; }
        public virtual List<Form> Forms { get; set; }
        public virtual List<Car> Cars { get; set; }
        public virtual List<Menu> Menus { get; set; }

public class Menu
    public int MenuID { get; set; }
    public int DomainID { get; set; }
    public int? ParentMenuID { get; set; }

    public virtual Menu Parent { get; set; }

    public virtual List<MenuTranslation> MenuTranslations { get; set; }
    public virtual Domain Domain { get; set; }

When I update-database expected fileds on Menu database is :


But it is populating as


So, there is Domain_DomainID and DomainDomainID1 fields are populating mysteriously.

Moving a file in microsoft webmatrix

As a project I'm working in microsoft webmatrix. The problem I had was my files were saving to My WebSites directory and not compiling so I changed the virtual path in IISExpress application.hostconfig to www.root. I was then able to compile lab15_1.cshtml and run it in the browser. I can see it in the solution explorer in visual studio 2010. Then I created lab15_2.cshtml but it won't run in the browser because it is in My Website directory. I don't know how I messed up, but I need to know how to move files to the solution explorer. I want to move lab15_2.cshtml to www.root but I don't know how. I'm thinking I should be able move it to the solution explorer to the website where lab15_1.cshtml is located. Does anybody know how I can do that? Much appreciation. Thank you in advance.

Populating HTML Table from JSON API in ASP.NET

So I am wanting to populate a table with items coming from a self made API. The API is working fine (showing / putting and deleting items,...), but I've failed to populate the existing table with the items.

What I'm using: - ASP.NET (MVC 5) - Entity Framework - JSON

What I have so far: url => /api/Film/ image I am asking this in a new thread since the solution should be working normally, I can't be bothered to learn this is in another method. I hope this won't be a problem.

My code:

Overview view:

<table id="Films" border="1">


 $(document).ready(function () {
                url: '/api/Film',
                type: 'GET',
                dataType: 'json',
                success: function (data) {
                    $.each(data, function (key, item) {
                        $('#Films').append("<tr><td>" + item.Id + "</td>" + "<td>" + item.Titel + "</td>" + "<td>" + item.Regisseur + "</td>" + "<td>" + item.Ranking + "</td><td><a href=\"#\" onclick=\"deleteFilm(" + item.Id + ")\">delete</a></tr>");

the (api)controller

// GET api/Film
public IEnumerable<Film> GetFilms()
    return db.Films.AsEnumerable();

What seems to be the problem in my code?

Using SDL MiniFuzz on MVC App

I'm currently working on a project where we are required to do Fuzz Testing, though I'm not entirely sure if you can or not on MVC. I was pointed to Microsoft's SDL MiniFuzz app for doing my Fuzz Testing, but quickly realized it accepts .exe, which I do not have.

My question is can MiniFuzz do any testing on a Web App? And if not, what is out there to do Fuzz Testing on Web Apps?

Why does Response.StatusCode = (int)HttpStatusCode.NotFound give me the generic error handler?

I catch and redirect 404 errors to an Error controller \ views with the following code.

        var routeData = new RouteData();
        routeData.Values["controller"] = "Error";
        routeData.Values["action"] = "HttpError";
        routeData.Values["exception"] = exception;          

        Response.StatusCode = 500;
        //if http 404 redirect to http404 action
        if (httpException != null)
            Response.StatusCode = httpException.GetHttpCode();
            switch (Response.StatusCode)
                case 404:
                    routeData.Values["action"] = "Http404";

In the error controller if I set Response.StatusCode = (int)HttpStatusCode.NotFound I get the generic error handler, not the view I returned. This only seems to happen in production. Any ideas why?

    public ActionResult Http404()
        //this line causes generic error handler
        Response.StatusCode = (int)HttpStatusCode.NotFound;

        var viewModel = new ErrorViewModel
            Description = "Hmm, the page you're looking for can't be found"

        return View("Error", viewModel);

How to find Key OutputCacheAttribute.ChildActionCache in mvc 3?

I have some problem:

This my action code:

[OutputCache(Duration = 3600, VaryByParam = "session")]
public PartialViewResult MiniAccountProfile(string session)
     //My business

     return PartialView("myPratialView", model);

In my PartialView, i have define enum "ActionCacheEnum.MiniAccountProfileAction" string:

<div class="menu-photo" data-cache="@ActionCacheEnum.MiniAccountProfileAction.ToString()" onclick="location.href = '/Extensions/User/Settings'">

And code find OutputCacheAttribute:

var item = OutputCacheAttribute.ChildActionCache.FirstOrDefault(x => x.Value.ToString().Contains(enumIndex));
    if (OutputCacheAttribute.ChildActionCache.Any())

This my idea. But i think performance its not good, because it must find into big string.

My question. How to find key of OutputCacheAttribute.ChildActionCache by ActionResult using its?

I try to using Response.RemoveOutputCacheItem, but it not work, and i read more topic example enter link description here. And They say: "Currently what you are trying to achieve is not possible in ASP.NET MVC 3. If you want to use donut output caching I would recommend you the following article. Hopefully this functionality will be added in ASP.NET MVC 4."

Thanks for helping me.

Slash in the ActionName attribute for MVC

Is it possible to have a slash in the ActionName attribute in ASP MVC?

e.g. I would like a paths


The reason for this is it mimics the navigation a user would use. But if I try to add the following to MyController it doesn't work.

public ActionResults A() {...}

Obviously without the attribute it wouldn't work either.

I've tried changing my RouteConfig.cs to

    name: "MyController",
    url: "MyController/MyAction2/{action}",
    defaults: new { controller = "MyController", action = "Index" }

But this affects all MyController paths. How can I get either a slash in the action name, or have the route config 'override' only come in to play when the action is MyAction2? mvc3 idle time out redirect to login automatically and store log out time

My application is in MVC3 version and i am stuck with the following Problem:

Scenario If user is idle for More than 2 min than he/she should be get log out and also at that moment I have to log his/her time (when their session got ended) to the database.

Problem: As I am storing user info in the session.So once user is redirected to login page their log out time need to be logged also need to consider scenario for multiple browser tabs opened at a moment.

Oauth Authentication

I have implemented OAuth token based authentication for my web api. In Oauth it used Entity framework for handling membership but I want to remove Entity framework and wish to implement my own membership. Is it possible to use OAuth without entity framework.

url of webapi, how to configure in mvc

I Have a url to a webapi, like this:"

and in the mvc project I have this files:

public class RouteConfig

        public static void RegisterRoutes(RouteCollection routes)

                name: "DefaultApi",
                url: "DefaultApi/{action}/{id}",
                defaults: new { controller = "Guestbook", action = "Index", id = UrlParameter.Optional, PageID = 1067 }


 public class WebApiConfig
        public static void Register(HttpConfiguration config)

            // Web API configuration and services

            // Web API routes

                name: "webapi/NavToDW",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }


and the Global.asax file:

public class Global : System.Web.HttpApplication
        public void Application_Start(object sender, EventArgs e)

            ViewEngines.Engines.Add(new Dynamicweb.AspNet.Views.RazorViewEngine());
            ViewEngines.Engines.Add(new Dynamicweb.AspNet.Views.WebFormViewEngine());
            // Fires when the application is started
            Dynamicweb.Frontend.GlobalAsaxHandler.Application_Start(sender, e);


        public void Session_Start(object sender, EventArgs e)
            // Fires when the session is started
            Dynamicweb.Frontend.GlobalAsaxHandler.Session_Start(sender, e);

        public void Application_BeginRequest(object sender, EventArgs e)
            // Fires at the beginning of each request
            //GlobalAsax.Application_BeginRequest(sender, e);

        public void Application_AuthenticateRequest(object sender, EventArgs e)
            // Fires upon attempting to authenticate the use
            Dynamicweb.Frontend.GlobalAsaxHandler.Application_AuthenticateRequest(sender, e);

        public void Application_Error(object sender, EventArgs e)
            // Fires when an error occurs
            Dynamicweb.Frontend.GlobalAsaxHandler.Application_Error(sender, e);

        public void Session_End(object sender, EventArgs e)
            // Fires when the session ends
            Dynamicweb.Frontend.GlobalAsaxHandler.Session_End(sender, e);

        public void Application_End(object sender, EventArgs e)
            // Fires when the application ends
            Dynamicweb.Frontend.GlobalAsaxHandler.Application_End(sender, e);

        public void Application_OnPreRequestHandlerExecute(object sender, EventArgs e)
            Dynamicweb.Frontend.GlobalAsaxHandler.Application_OnPreRequestHandlerExecute(sender, e);

So I can can connect. But I cant go to the specific link, like this:

the outcome is this:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Message>An error has occurred.</Message>
The object has not yet been initialized. Ensure that HttpConfiguration.EnsureInitialized() is called in the application's startup code after all other initialization code.

So what I have to change?

Can't create component as it has dependencies to be satisfied. Parameter which was not provided

I have just started using Windsor to resolve dependency. But i am getting below error while passing string value in my Controller.I checked couple of similar Windsor Post but no luck.

public class HomeController : Controller
    public readonly String _A = string.Empty;
    public HomeController(string A)
        this._A = A;        


public void Install(IWindsorContainer container, IConfigurationStore store)


public class WindsorControllerFactory : DefaultControllerFactory
        private readonly IKernel kernel;

        public WindsorControllerFactory(IKernel kernel)
            this.kernel = kernel;

        public override void ReleaseController(IController controller)

        protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
            if (controllerType == null)
                throw new HttpException(404, string.Format("The controller for path '{0}' could not be found.", requestContext.HttpContext.Request.Path));
            return (IController)kernel.Resolve(controllerType);

Do i need to wrap 'A' inside a class and resolve it's respective Interface ?

Code generated by RazorGenerator not executed, script code still is

So I installed RazorGenerator with nuGet and added the VS extension (thanks to Visual Studio cannot find custom tool RazorGenerator).

Just to try it out on my existing mvc app, I changed the custom tool to RazorGenerator on one of the views, and generated the code with the right-click option "Run Custom Tool". The code was indeed created.

I then build the entire app and tried running it, setting a break point in both the old razor script and the new pre-compiled code. Much to my surprise, it was still running the old script code, not the new. Am I missing a step somewhere to switch over execution to the new code. The documentation is a little skimpy, but you would think something crucial like this would have been mentioned if needed. I know it calls the bootstrap code in App_Start using WebActivatorEx.PostApplicationStartMethod(), or at least it did so once, doesn't seem to do it on every debug start though, not even after an iisreset. If I try to delete the source razor view the ajax call fails when returning result, so it is obviously not using the precompiled code. Am I missing a step somewhere?

How to add buttons to each row in a dataTable?

I've added a table to my which dynamically creates the table columns and rows. What I'm trying to do now is add an Edit and Delete button to each row in that table.

In order to achieve that I tried placing two td's containing the buttons wihthin the for..each loop that creates the table rows.:

@foreach (var cell in row.ItemArray) {
  <td style="word-wrap:break-word;font-size:11px">@cell.ToString()</td>
  <td><a class="btn-success">Edit</a></td>
  <td><a class="btn-danger">Delete</a></td>

But this add two buttons to each cell in every row which is not the intended outcome.


How can buttons be dynamically created for each row in a data table?

Razr markup for table:

 <table id="escalation" class="table table-striped table-bordered" cellspacing="0" width="100%">
            @foreach (System.Data.DataColumn col in Model.Columns)
                <th style="font-size: 12px; border-right: 1px solid #7591ac; ">@col.Caption</th>

        @foreach (System.Data.DataRow row in Model.Rows)
                @foreach (var cell in row.ItemArray)
                    <td style="word-wrap:break-word;font-size:11px">@cell.ToString()</td>
                    <td><a class="btn-success">Edit</a></td>
                    <td><a class="btn-danger">Delete</a></td>

WebActivatorEx.PostApplicationStartMethod() not called at startup

Trying to attach a WebActivatorEx.PostApplicationStartMethod() to an existing MVC 3 application, in particular RazorGenerator.

[assembly: WebActivatorEx.PostApplicationStartMethod(typeof(TiPSViewWeb.RazorGeneratorMvcStart), "Start")]

namespace TiPSViewWeb {
    public static class RazorGeneratorMvcStart {
        public static void Start() {
            var engine = new PrecompiledMvcEngine(typeof(RazorGeneratorMvcStart).Assembly) {
                UsePhysicalViewsIfNewer = HttpContext.Current.Request.IsLocal

            ViewEngines.Engines.Insert(0, engine);

            // StartPage lookups are done by WebPages. 

However this code is never executed during startup. I tried creating a new basic mvc application and installed Razor Generator into it, and the application is breaking nicely in the Start(). Am I missing a step here in order to make the app server call the right function? Is there anything that might be overshadowing that call?

I have this in Application_Start():

protected void Application_Start() { RouteTable.Routes.Ignore("{resource}.axd"); AreaRegistration.RegisterAllAreas();



Application["ReportTasks"] = new Dictionary<long, Thread>();
Application["ReportTokens"] = new Dictionary<long, string>();

Security Exception in nopCommerce with Full Trust set

I am using nopCommerce 3.70 on Godaddy's shared Hosting. I have had this website up and running for the last month or so, no problem until just the other day. All of a sudden I am getting a security exception error, that would normally tell me that my site is not set to "Full Trust"; however, it is and I even called Godaddy to have them verify that it was actually set. I can not for the life of me figure out why this site will not work and I even re-downloaded, unblocked and republished this site (everything except the App_Data folder, don't want to loose the db). Same error:

[SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.] System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) +0

in debug mode it says the issue is at line 31

Line 29: Line 30: Line 31: @Html.Widget("header_links_before") Line 32: @T("HomePage") Line 33:

Has anyone else ever encountered this issue? Any ideas about what else I can try to fix this?

Also, after about 4 calls with GoDaddy they are saying that the website is trying to perform a task that either the website itself doesn't allow or the server wont allow, because it's shared hosting.

Any help with this would be so greatly appreciated. Thank you in advance.

Display multiple div after Http post ASP.NET MVC3 RazorView

I am a new to ASP.NET MVC, I had been working on ASP.NET Webform. I have couple of questions with respect to design in ASP.NET MVC. [Note I am working on ASP.NET MVC3 Razor View Engine].


I am creating a search panel. So When the search is submit, it search for different information. Example: An account search. So in search I am providing information and the search would result, Account details (different panel), Account Balance (different panel), all activities belongs to that account (seperate panel)

  1. How should I display the three panels after the search is submitted?
  2. Displaying activities search result would have the feature to edit each item as well. So should I keep the activities result in partial view or in the same view?
  3. My two panel (Account details and account balance) would always be displayed after the search is performed. But they should be hidden before the search is performed. But for activities if the result is null, display a message for "No result found". How should I implement this feature?

I know in Webform it's easy to make visible panel if the search is conducted and display the information. But how to achieve in ASP.NET MVC, kind a new for me.

Any help would be really appreciated.

passing List object that created in controller to Index view

I have a problem to create a advance search in mvc, because I am new in mvc so I made some mistake in code in my question (but I made a lot of complicated sit in in vb or c#), I fixed my code with Mark's link ( , because some friend answer to my first wrong question that was solved by my self and it was confused I decided to ask new situation of my problem.

Actually now my search is working probably, I summarize the code as below:

My search view is:

@model IEnumerable<WomenNew.Models.News_>
    ViewBag.Title = "AdvanceSearch_";
@using (Html.BeginForm())
    @Html.TextBox("Details", "this is value")
     <input type="submit" value="Search" />

In controller this view call it's method:

    public ActionResult AdvanceSearch_(string Details)
        //List<News_> news_ = new List<News_>();
        if (Deatails != null)
            newsList = db.News_.Where(x => x.Deatails.Contains(Details)).ToList();
            return RedirectToAction("Index", "News_");
            return View("AdvanceSearch_");

I had to define a public static variable because I don't know the correct way and I ask this question to know how the correct is.

public static List<News_> newsList = null;

And in my ActionResult Index I add a condition to know either newesList is null otherwise I pass the ListObject to Index view and sear work fine

    public ActionResult Index(string searchBy, string search )
        if(newsList != null)
            return View(newsList);

I tried to not define public Variable but with passing between AdvanceSearch_ and Index the variable became null even ViewBag I checked it became null, I thought in protected override void Dispose(bool disposing)

method this is happened but I checked in another point it changed to null One friend told

A public static field is a single memory location available to every user of the application. Every user shares the same value.

I appreciate If anybody con help me how I can pass a List of Object from second block in this question (ActionResut Advance Search) to third block (Index ActionResult) or give me a link of code or a link of Walk trough for search in mvc which shows advance search with more fields. All I found out is a simple search inside the same view. A very kind friend (mgebhard) guide me to use TempData and he gave me a link :this is a tutorial mvc and is very valuable
Thanks a lot

How do I fake the call to Configuration to setup the Job Storage. I have been looking at the Hangfire documentation and they are a little cryptic in this area and mention that job storage should be set up something like this

GlobalConfiguration.Configuration.UseSqlServerStorage("<connection string or its name>");
using (new BackgroundJobServer())
   BackgroundJob.Enqueue(() => ProcessReport(oReportRequest, JobCancellationToken.Null)));


however GlobalConfiguration is not known anywhere in the controller or unit test.

Check session object and return accordingly

I have following code in my controller actions. I have more than 15 controllers and more than 40 actions through out the application. Instead of checking session for each and every action, how nicely and bett

//Check if USER SESSION object is available
            if (Session["user"] != null)
                return View();
                return RedirectToAction("logout", "Home", new { area = "Common", value = "SessionTimeOut" });

I just don't want to repeat the if statement for all 40 actions. Any better way of doing this?


Can't seem to get form values (in view) to the controller

I have 2 bits of code here.

This is my controller at the moment:

using System;
using System.Net.Mail;
using System.Web.Mvc;
using WebMatrix.Data;

namespace Best_prototype_01.Controllers
    public class RecrutaController : Controller
        public ActionResult Index()
            return View();

            protected void btnSubmit_Click(object sender, EventArgs e)
                MailMessage Msg = new MailMessage();
                // Sender e-mail address.
                Msg.From = new MailAddress(txtEmail.Text);
                // Recipient e-mail address.
                Msg.Subject = txtSubject.Text;
                Msg.Body = txtMessage.Text;
                // your remote SMTP server IP.
                SmtpClient smtp = new SmtpClient();
                smtp.Host = "";
                smtp.Port = 587;
                smtp.Credentials = new System.Net.NetworkCredential("", "yourpassword");
                smtp.EnableSsl = true;
                //Msg = null;
                lbltxt.Text = "Thanks for Contact us";
                // Clear the textbox valuess
                txtName.Text = "";
                txtSubject.Text = "";
                txtMessage.Text = "";
                txtEmail.Text = "";
            catch (Exception ex)
                Console.WriteLine("{0} Exception caught.", ex);



And this is the view that's supposedly associated with it (the part that matters anyways):

<form id="form1"  >
        <table cellspacing="2" cellpadding="2" border="0">
            <tr><td></td><td><b>Contact Us Form</b></td></tr>
            <tr><td><b>Name</b></td><td><asp:TextBox ID="txtName"   /></td></tr>
            <tr><td><b>Email</b></td><td><asp:TextBox ID="txtEmail"   /></td></tr>
            <tr><td><b>Subject</b></td><td><asp:TextBox ID="txtSubject"   /></td></tr>
            <tr><td valign="top"><b>Message</b></td><td> <asp:TextBox ID="txtMessage" Rows="5" Columns="40" TextMode="MultiLine"   /></td></tr>
            <tr><td></td><td><asp:button ID="btnSubmit" Text="Submit"   onclick="btnSubmit_Click" CssClass="Button" /></td></tr>
            <tr><td colspan="2" style=" color:red"><asp:Label ID="lbltxt"   /></td></tr>

Can someone point me in the right direction? I have no clue what I'm doing wrong.

A generic error occurred in GDI+, Getting this exception in my code when i try to save optimized image on server

Here is my code below which i am using to redraw and save the image.

Bitmap bitmap = new Bitmap(HttpContext.Current.Server.MapPath(filePath + Path.GetFileName(fileName)));

MVC EF Adding object to database

So this is a continuation of the question here

I am trying this below:

public DbSet<User> Users { get; set; }
public DbSet<Sport> Sports { get; set; }
public DbSet<Team> Teams { get; set; }

  • I can have many Sports
  • I can have many Teams in a Sport
  • I can have many Teams in a User
  • I can have many Users in a Team


public int ID { get; set; }
public List<Team> Teams { get; set; }


public Team(int ID, int SportID, int Wins, int Losses, String Name, String Description, double Reputation, List<User> Members, byte[] TeamLogo)
     this.ID = ID;
     this.SportID = SportID;
     this.Wins = Wins;
     this.Losses = Losses;
     this.Name = Name;
     this.Description = Description;
     this.Reputation = Reputation;
     this.Members = Members;
     this.TeamLogo = TeamLogo;
public int ID { get; set; }
public List<User> Members { get; set; }
public int SportID { get; set; }


public int UserID { get; set; }
public List<Team> Teams { get; set; }


protected override void OnModelCreating(DbModelBuilder modelBuilder)
        // Adds middle table between Users and Teams
            .HasMany<Team>(t => t.Teams)
            .WithMany(m => m.Members)
            .Map(w => w.ToTable("UserTeam")

public void addTeam(Team team, String sport)
        // Add the team to the correct sport


model.NewTeam = new Team(0, db.getSportID(model.SelectedSport), 0, 0, model.TeamName, model.TeamDescription,
                   100, new List<User>() { model.currentUser }, model.ActualImage);
db.addTeam(model.NewTeam, model.SelectedSport);


It adds a record to the Teams table just fine. It adds the record to the UserTeam table just fine. The problem is that it is also adding a new record to the User table as well so I have repeating users in my User table. Also, when I query the Teams Table, I get a null List Members so EF isn't properly getting the Members of each team from the Many-Many table.

Send Birthday E-Mail

public bool BirthdayEmail (int userId, int birthdate)
 var userbirthday = db.Contacts.Where(x => x.CustomerId == birthdate).FirstOrDefault();
return userbirthday;

creating custom logic for focusing html elements while validating form

I have been stuck in somewhere around validating the form. I have a nice 10-11 fields in my .cshtml page in MVC. Those fields are using data anotations from model and here I am using client side validations using jquery and unobtrusive javascript. So, validations are firing up very good on submit but we need to implement a logic where a user will click on the submit button but the page will automatically drags the user to the location of mandatory field.

Assume that all 11 fields in my form are mandatory. user has filled the first two and left the third blank .So on submitting the form, the cursor should focus to that control with the validation message.Due to the length of the page, it should be scrolling up and down accordingly. And if suppose only first two fields are filled and others are empty, the validation message should show the 3rd field with the focus on control and then if user filled the 3rd field and hit save, it should focus to the fourth field.

On one instance it looks easy and I am trying it with following code snippet on click of submit button.

AS this is the class which mvc uses when validation fires, I select element from the first class like below:

 var element = $('#' + $('.input-validation-error:first').attr('id'));

once I get the element then I am using the below code:

 if (element.selector !== '#undefined') {

// The class "RequiredFeildDropdown" is applied to the control so that I can
 check if that is kendo dropdown and I should focus to that kendo control of the element.

        if (element.hasClass("RequiredFeildDropdown")) {

// This class "RequiredFeildDate" has been applied to check whether the kendo control is datepicker
so that I can focus it.

        else if (element.hasClass("RequiredFeildDate")) {

// So here comes the real problem.The primaryaddressData contains the collection of objects. Actually my page also consists of some table elements that i have created using for loop.

So, while validating , if primaryaddressData.length have count < 1, this div should show.Actually there should be atleast one primary address. The div which have table elemets is "primaryaddressErrorMessage"

 else {
        if (primaryaddressData.length >= 1) {
        } else {
                scrollTop: $("#primaryaddressErrorMessage").offset().top
            }, 'slow');
            isValid = false;


I am going very hard through this. There might be someone who has also faced this problem in past. So, it could be a duplicate question but I asked it for this particular scenario. Please let me know if some more explanation is required.

Installing Nuget package throws "An item with the same key has already been added" error

I have an MVC3 application which has a mixture of directly referenced binaries with paths such as:


and binaries installed via NuGet like this:


I am trying to get the app to build only using NuGet so we don't have to move dlls into remote repositories

Taking ActionMailer as an example, here is what I am doing

How can i overload Index in MVC

I've Index page which is included Blogs from database. Firstly, if i dont give the categoryID then all blogs must come to index page. If i give the category then i want to display blogs by categoryID so i need use Index overload.

public ActionResult Index(){List<Blog> blogs = db.Blogs.ToList();}
public ActionResult Index(int ID){List<Blog> blogs = db.Blogs.Where(x=>x.CategoryID==ID).ToList();}

But when i want to display all blogs the error come like this:

The current request for action 'Index' on controller type 'HomeController' is ambiguous between the following action methods: System.Web.Mvc.ActionResult Index() on type SosyalSozluk.Areas.Blog.Controllers.HomeController System.Web.Mvc.ActionResult Index(Int32) on type SosyalSozluk.Areas.Blog.Controllers.HomeController

How to default my entire application should run in IE 10 on server?

I deployed mvc application to the server. Now I would like to make my application should run default to IE10?

Thanks for the help in advance.

DB connection on the rel server?

    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-annaBevzenkoPortfolioMVC-20160425034146.mdf;Initial Catalog=aspnet-annaBevzenkoPortfolioMVC-20160425034146;Integrated Security=True" providerName="System.Data.SqlClient" />

- that is the connection which I use on my local machine. But when I deploy my app to the real server, there are problems with DB. For truth, I know nothing about DB-setup. As I understand, I should create a new MySql database using my hosting provider API and then change the coonection string in web.config? I've tried that way, but it doesn't work. I just dont understand what am I doing wrong?

P.S. The connection string which was generated by my hosting provider when I created a new MySql DB: <add name="DefaultConnection" connectionString=";Database=db_9fcf5d_default;Uid=9fcf5d_default;Pwd=<my_password>;" providerName="System.Data.SqlClient" />.

MVC AJAX Updating

I am trying to update my page with ajax and have a form inside my page but whenever I return a partial view, it returns on a new page.

The code is as follows:

..Other code in my view
<div id="createTeam">
    @using (Ajax.BeginForm("CreateTeam", "Lobby", new AjaxOptions
        InsertionMode = InsertionMode.Replace,
        UpdateTargetId = "createTeam"
    }, new { id = "formCreateTeam" }))
        <button id="btnCloseCreateTeam" class="btnClose">X</button>
        <div id="leftSide">
            <p>Team Logo</p>
            <img id="imgTeamLogo" src="~/Content/Images/default_logo.png" />
            <div id="fileUpload">
                <span class="upload">Upload</span>
                <input type="file" id="uploadTeamLogo" name="TeamLogo" accept="image/*">
        <div id="rightSide">
            <p id="lblError" class="txtRedMedium">@Model.Error</p>
            @Html.ValidationMessage("TeamName", new { @class = "textRedSmall" })
            <label class="textBlackMedium">Team Name:</label><br />
            <input type="text" id="editTeamName" name="TeamName" class="textbox"><br />
            <label class="textBlackMedium">Team Description:</label><br />
            <textarea id="editTeamDescription" name="TeamDescription" class="textarea"></textarea><br />
            <input type="submit" value="Create Team" class="buttonCreateTeam">
            <input type="text" value="@Model.Sport.Name" name="sport" />
...Other code in my view

Controller function:

public PartialViewResult CreateTeam(LobbyMatchesViewModel model, String sport)
        model.Sport = new Sport();
        model.Sport.Name = sport;
        model.TeamCreated = false;

        /****************** Create Team *******************/

        // Check if team name is available
        Team tempTeam = db.getTeamByName(model.TeamName, sport);
        if (tempTeam != null)
            // Team name for this sport is already taken
            model.Error = "Team name is already taken!";
            return PartialView("CreateTeam", model);
        // Add image to user
        if (model.TeamLogo != null)
            byte[] data = new byte[model.TeamLogo.ContentLength];
            model.TeamLogo.InputStream.Read(data, 0, model.TeamLogo.ContentLength);
            model.ActualImage = data;
        model.TeamCreated = true;
        model.NewTeam = new Team(0, db.getSportID(sport), 0, 0, model.TeamName, model.TeamDescription, 100, null, model.ActualImage);
        db.addTeam(model.NewTeam, sport);
        return PartialView("CreateTeamSuccess");

I don't understand why it is loading a new page rather than just the div "createTeam". It is sending me to a page Lobby/CreateTeam instead of Lobby/Matches which is what I am on when I submit the form. Shouldn't Lobby/CreateTeam just render a partial view back to Lobby/Matches?

Is ControllerBase.Execute(RequestContext) obsolete in MVC5?

I am upgrading a web site from MVC3 to MVC5. I simply used NuGet to install Microsoft.AspNet.Mvc version 5.2.3 and everything seemed to be working fine. But upon closer examination I noticed that this code was no longer running:

public abstract class BaseController : System.Web.Mvc.Controller
    protected override void Execute(RequestContext requestContext)

I found this lifecycle documentation (linked from here) which seems to confirm that Execute is no longer called by MVC.

However, this documentation is unclear, saying

This method is an implementation of Execute. You typically do not have to override this method. Override Initialize or ExecuteCore instead.

I would expect it to say "This method is no longer called by the MVC framework as of version 5 (or maybe 4)." Perhaps even mark it [Obsolete], although there may have been good reasons not to do that.

Furthermore, my testing shows that ExecuteCore does not get called either! It looks like OnActionExecuting is the best place to move the code that used to live in Execute, is that correct?

get checked check-box value using form-collection

I have check-box input field on the view page as given below-

<input type=@item.InputType.ToString().Trim().ToLower() id="@item.AdminAnswers.ElementAt(i).Answer" value="@item.AdminAnswers.ElementAt(i).Answer" name="@item.Id"></input>@item.AdminAnswers.ElementAt(i).Answer

and in the controller am getting data using form collection as given below-

public ActionResult Index(FormCollection data)
        foreach (var item in surveyDatas)
            if(item.InputType.ToString().Trim().ToLower() == "checkbox")
                var dev =item.NumberOfChoice;
                for (int i = 1; i < dev; i++)
                    //here I need to iterate checked checkbox value
            myclientanswer.DevAnswers = devAnswer;              
        return View("LoginResult");

How can I iterate only checked check-box values over there??

Filtering the records in c# from view

I am having a view which is like

CREATE view [dbo].[vw_myList]


SELECT tblOrg.locationName Name, 

       tblOrg.locationID Id,

       from tables with some joins.

as you can see I am not having any accepting paramameter for this view but now I have one condition on some another web page that will be using this view but it needs to filter the selected records from this view using locationId

like where locationId = @argument

I have tried to use it like below:

       var locationList = this._Service.GetlocationLists();

List<mymodel> objlist = new List<mymodel> objlist

// This gets all records

  var list= locationList .Select(m => new mymodel
                 name = Name, id= Id

but i wanted to use it like but it is not working

  var list= locationList.where(m=> => new mymodel
                 name = Name, id= Id

Why Aspx view engine is faster than razor view engine in MVC?

I see lot of Differences Between Razor View Engine and ASPX View Engine But I am not able to understand that why Web Form Engine is faster than Razor Engine ? What is the reason behind it ?

Can MVC deserialize the json string which is having perl_script naming convention

We are working with the third party vendor who is passing following object as part of Form post

    "application": 123,
    "order_reference": "01234",
    "new_status": "initialize"

As this is not the standard naming convention in C#, i created following model.

public class Response
    public string Application {get; set;}

    public string OrderReference {get; set;}

    public string NewStatus {get; set;}

And i have below code in controller.

public Notify(Response response)
   // code.

The request is coming to the above method, but the object is not deserializing, I could see that, only application property is getting mapped.

Could any one please let me know, whether i can make it work with the model i have created or do i have to create the same model as the response is coming?

MVC ReturnUrl link error

I'm working on ReturnUrl in mvc but i have some url link error.

a href="/User/Login?returnurl=/Forum/Detail/@item.ID" with this link going to Login view and carrying returnurl parameters.

In the login page i catch returnurl querystring with this code

string url = Request.QueryString["returnurl"];

        if (ModelState.IsValid)
            if (db.Users.Any(x => x.Mail == model.EMail && x.Password == model.Password && x.IsDelete == false))
                FormsAuthentication.SetAuthCookie(model.EMail, true);

                if (!string.IsNullOrEmpty(url))
                    return RedirectToAction(url);
                return RedirectToAction("Index", "Home");

After when i click sign in i cannot go back to my first url. Link turn this http://localhost:61476/User/Forum/Detail/3

I want to turn back this url: http://localhost:61476/Forum/Detail/3

Working with tempdata in mvc

As I have read that once you set a tempdata, it will last till next request and if you need to use it more then we need to use keep. But in this situation there is somewhere my tempdata is being lost.

The scenario is below:

I have a view and corresponding to that I have a action method in my controller and here I just set a tempdata as below:

Controller class:

public actionresult myview()
   tempdata["Empid"]= sourceid;

The view consists of several renderAction as below and all these actionmethods in controller return some partialviews


Now in partialviews, I have several ajaxified calls suppose in one of the partialview , I have a post method using ajax like below:

$.post("action", "controller",{}});

Please ignore syntactical mistakes as I only have problem in understating the logic of tempdata.

So, coming to above, now the post methods have actionmethods that uses the tempdata that i have set when my view page loads i.e tempdata["Empid"] because this tempdata is needed to get details of employee.

So, it gets the data, reurn json formatted data and I show it in view perfectly. Uptill here everything is fine. Now, I have one of the partialviews that uses the ajax post to hit controller which is not the same controller but a different cs file. Here this tempdata goes off.

Why is it happening so..
