Undefined Values in Kendo Dropdownlist - telerik-mvc

Question

I am using Telerik's dropdownlist in my MVC application View. I am facing two problems:
1) When I run my application, I find every value of kendo dropdownlist is "Undefined".
This is the code for my View:
#model IEnumerable<EulenMgrKendoUIMvcApplication.Dominio.Tablas.DelegacionProductoUsuario>
#(Html.Kendo().DropDownListFor(d=>d)
.Name("IdDelegacionProductoDrpDwn").HtmlAttributes(new { #style = "font-size:12px" })
.DataTextField("IdDelegacionProducto")
.DataValueField("IdDelegacionProducto")
**.BindTo((System.Collections.IEnumerable)ViewData["IdDelegacionProducto"]))**
This is my controller, where I populate the dropdownlist:
public class DelegacionProductoUsuarioController : Controller
public ViewResult List()
{
IEnumerable<DelegacionProductoUsuario> delegaciones = DelegacionProductoUsuario.GetAll();
**PopulateDelegacionProducto();**
return View(delegaciones);
}
private void PopulateDelegacionProducto()
{
List<Int64> IdDelegacionProductoList = new List<Int64>();
foreach( DelegacionProductoUsuario d in DelegacionProductoUsuario.GetAll()){
IdDelegacionProductoList.Add(d.IdDelegacionProducto);
}
ViewData["IdDelegacionProducto"] =IdDelegacionProductoList ;
}
}
>I am debugging the application and the controller is passing to the view the proper values,so I don't understand why it doesn't show them.
2) Second problem: I insert this Dropdownlist in one of the columns of a kendo grid with no success.
In it's place it appears a common label. Here is the code for my Grid, I mark in Bold the column where I try to show my dropdownList:
#(Html.Kendo().Grid(Model)
.Name("Grid")
.Columns(columns=>
{
columns.Bound(d => d.BorradoLogico).Title("Borrado logico");
columns.Bound(d => d.FTick).Title("Ftick");
**columns.Bound(d => d.IdDelegacionProducto).Title("IdDelegacionProducto").EditorTemplateName("IdDelegacionProductoDrpDwn");**
columns.Bound(d => d.IdUsuario).Title("IdUsuario");
})

Answer 1

How does that 'DelegacionProductoUsuario' class look like? Does it have property named 'IdDelegacionProducto' ? It looks like you have not set the dataValueField correctly.
As for the second question, where did you put that EditorTemplate (is it in the Shared/EditorTemplate or in a EditorTemplates folder? More info about editor template can be found here.

Dear Petur: thanks a lot for answering. On regard to your answer:
My class DelegacionProductoUsuario does have a property called IdDelegacionProducto. On regard to your question "where I place the EditorTemplate" , I don't understand what you mean, I place it in the view that Lists all of my DelegacionProductoUsuario . Please keep on helping me. Thanks a lot Petur.
