[Solved] Can't Get Editor Template To Display

[Jerry]

Seems this should be pretty simple.  Each custodian should have a default SecurityIDType assigned to them.  I want the SecurityIDType to be a picklist in the grid when inserting or editing.  I've included what I believe to be all the related code below.  If someone can help me figure out why the DropDownList never shows up, that would be great.

All of the binding and editing features seem to work, otherwise.

Thanks.

View Models:

public class CustodianViewModel
{
  [ReadOnly(true)]
  public int ID { get; set; }

  [Required]
  public string Description { get; set; }

  public bool Deleted { get; set; }

  [UIHint("SecurityIDTypePicklist"), Required]
  public SecurityIDTypeViewModel DefaultSecurityIDType { get; set; }
}

public class SecurityIDTypeViewModel
{
  public int ID { get; set; }
  public string Description { get; set; }
  public bool Deleted { get; set; }
}

View (Index.cshtml)

@model IEnumerable<CamBakWeb.ViewModels.CustodianViewModel>

Hello Jerry,

 This sounds like the project described in this blog post.

All the best,

Yes, it sounds like it, but I still can't get it to work.  I'm even trying to follow the code that appears to work in the demo solutions that's installed by the Telerik setup.  But there's so much going on that project with MVC being combined with ASPX that I'm obvioulsy not following it properly.  I find it hard to believe that there's not a simple example of how to make this work.  I've been searching for two days.

Any further advice would be appreicated.

Thanks.

Jerry

Hello Jerry,

 You probably need to create a custom editor template for your root view model as ASP.NET MVC will not invoke the child editor template out of the box (as described in the blog post). A sample project is attached to that very blog post and you can play with it.

You can also check the custom popup edit form code project which also uses as custom editor template.
