To save someone trouble:  this "Delegate 'System.Action<Telerik.Web.Mvc.UI.TreeViewItem,[xxx]>' does not take '1' arguments" error seems to be the one you'll get for basic problems with your treeview's declaration.  

I was also getting this same error, but mine was because of a type mismatch.  I was trying to bind an integer field to item.Value, which is a string.

If neither of our issues above were the problem for you, narrow down your problem by commenting out parts of the treeview declaration until it starts working, and then uncomment sections of it until it breaks again.
