下拉列表在剑道网格不工作

我试图使用单元格编辑和使用http://demos.telerik.com/aspnet-mvc/grid/editing-custom，但无法找到我的部分视图，下拉列表应该呈现。

部分视图(Testview.cshtml)

   @using Kendo.Mvc.UI
 @(Html.Kendo().DropDownList()
        .Name("ResourceType") // Name of the widget should be the same as the name of the property
.DataValueField("Id") // The value of the dropdown is taken from the EmployeeID property
.DataTextField("Name") // The text of the items is taken from the EmployeeName property
    .BindTo((System.Collections.IEnumerable)ViewData["defaultResourceType"]) // A list     of all employees which is populated in the controller

)

这是我的网格:

  @(Html.Kendo().Grid<RMS.Admin.ViewModel>()
  .Name("ResourceGrid")
  .Columns(columns =>
  {
      columns.Bound(c => c.ResourceId).Hidden();
      columns.Bound(c => c.ResourceName);
      columns.Bound(c => c.Descritption);
      columns.Bound(c => c.ResourceType.Name).ClientTemplate("#=ResourceType.Name#");
      columns.Bound(c => c.Approved);
      columns.Bound(c => c.IsEnabled);
      columns.Command(command =>
      {
          command.Edit();
          command.Destroy();
      }).Width(172).Title("Edit/Delete");
  })
  .ToolBar(toolbar => toolbar.Create())
  .Editable(editable => editable.Mode(GridEditMode.InCell))
  .Scrollable()
  .Sortable()
  .Pageable(pageable => pageable
      .Refresh(true)
      .PageSizes(true)
      .ButtonCount(5))
  .DataSource(dataSource => dataSource
      .Ajax()
      .Model(model =>
      {
          model.Id(s => s.ResourceId);
          model.Field(s => s.ResourceType).DefaultValue(ViewData["defaultResourceType"] as RMS.Admin.ViewModel.ResourceTypeId);
      })
      .Create(update => update.Action("CreateResource", "Home"))
            .Read(read => read.Action("ReadResource", "Home"))
            .Update(update => update.Action("SaveSystem", "Home"))
            .Destroy(destroy => destroy.Action("RemoveSystem", "Home"))
    )

)

这是我的模型的一部分:

  public string ResourceUserId { get; set; }
    [UIHint("Testview")]
    public ResourceTypeId ResourceType { get; set; }

这是在我的控制器，我绑定的数据:

    private void GetResourceTypeId()
    {
        //string [] list = new string[]{"Image", "Document", "Other"};
        IList<ViewModel.ResourceTypeId> list = new List<ViewModel.ResourceTypeId>();
        var a = new ViewModel.ResourceTypeId
        {
            Name = "Image",
            Id = 1
        };
        var b = new ViewModel.ResourceTypeId
        {
            Name = "Document",
            Id = 2
        };
        var c = new ViewModel.ResourceTypeId
        {
            Name = "Other",
            Id = 3
        };
        list.Add(a);
        list.Add(b);
        list.Add(c);
        ViewData["defaultResourceType"] = list.First();    
    }

我得到这个错误时，试图渲染网格:您正在查找的资源(或其依赖项之一)可能已被删除、名称已更改或暂时不可用。请查看以下网址，并确保拼写正确。

我错过了什么?
