Question

This is my Viewmodel

public class IndexViewModel
{
    public string QuestionText { get; set; }
    public string Sname { get; set; }
    public string Cname { get; set; }
    public int CID { get; set; }
    public int SID { get; set; }
    public Question question { get; set; }
    public CoreValue corevalue { get; set; }
    public SubjectType subjecttype { get; set; }

}

and inside my view I have problems this code aint working:

@model NKI3.ViewModels.IndexViewModel

@using (Html.BeginForm()) {
<fieldset>
<div class="editor-label">
@Html.DropDownListFor(model => model.Sname)
</div>
</fieldset>
}

The error message I get is ” No overload for method ‘DropDownListFor takes 1 argument “

Whats the solution?

   public class AdminController : Controller
{
    AdminRepository AdminRep = new AdminRepository();

    public ActionResult Index()
    {
        List<Question> ListQuestions = AdminRep.GetAllQuestions();
        var model = new AdminIndexViewModel();  
        model.QuestionList = new List<QuestionViewModel>();
        foreach (var item in ListQuestions)
        {
            var QuestionViewModel = new QuestionViewModel();
            model.QuestionList.Add(QuestionViewModel);
            QuestionViewModel.QuestionText = item.QuestionText;
            QuestionViewModel.QuestionId = item.Id;
            QuestionViewModel.CoreValues = new List<string>();
            foreach (var CoreValues in item.CoreValue)
            {
                QuestionViewModel.CoreValues.Add(CoreValues.Name);
            }
            QuestionViewModel.SubjectTypes = new List<string>();
            foreach (var SubjectType in item.SubjectType)
            {
                QuestionViewModel.SubjectTypes.Add(SubjectType.Name);
            }
        }
        return View(model);
    }

View:

@foreach (var item in Model.QuestionList) {
<tr>
    <td>
    @Html.DisplayFor(modelItem => item.QuestionText)
    </td>
    <td>
    @string.Join(", ", item.SubjectTypes)
    </td>
    <td>
    @string.Join(", ", item.CoreValues)
    </td>
    <td>
        @Html.ActionLink("Edit", new { id = item.QuestionId}) |
        @Html.ActionLink("Delete", new { id = item.QuestionId })
    </td>
</tr>
