Hi,
I have 2 questions regarding combo box:
1) I have a View (Create.cshtml) which receives a view model, let's call it ComplexViewModel. From this view I call the editor template view for a member of the ComplexViewModel, which is another view model, let's call it: SimpleViewModel
The editor template view in ~/Shared/EditorTemplates:
The problem is that client-side validation for the combobox in the Editor Template view does not work. Why not?
2) How do I set the selected value of the ComboBox to an item that is not part of the list it is binded to:
Example from question 1). Let's say that "Model.Lists" (which is an IEnumerable<string>) contains the following values: A, B, C. But when the the combobox is rendered by the editor template I want it to have the the selected value set to "Default", which is not in the list it is binded to. It is interesting that I tried setting the value with something outside the list in the "Create.cshtml" view like this:
@Html.Telerik().ComboBoxFor(x => x.Project).BindTo((IEnumerable<SelectListItem>)new SelectList(Model.Lists as System.Collections.IEnumerable, "Default"))
This works in the "Create.cshtml" view, but the exact same line of code does not work when put in the EditorTemplate view (the one mentioned at 1)

Wonder why Telerik ignoring this question?! After searching for a few days now, I see many people have the same issue and I see no solution for it by telerik or by anybody else.
I am thinking of dumping Telerik controls altogether and switching to something more predictable, less buggy and better supported. Support is the main part of your controls, guys, not controls themselves. In other words, If you don't support it, no one will ever use it.
Hope this makes sense to you.

This seems to be a problem in the Kendo toolkit as well. I've posted a support request and let's see where it goes from there but I must say I'm pretty frustrated about this. I'm currently evaluating Kendo; I know the server wrappers are in beta but this problem has also been present in the standard MVC extensions since day dot.
Client validation for Editor Templates seems like a fairly basic requirement and it just doesn't work. Can't believe more people haven't come across this - they must all be binding to simple forms.

@(Html.Telerik().ComboBoxFor(c => c.EmployeeID)
.Name(
"EmployeeID")
.InputHtmlAttributes(
new { name = "EmployeeID" })
<input name="EmployeeID-input" ....
I have changed name property by using inputHtmlAttributes, same as viewmodle property name.
It worked for me.
