In your on-line Silverlight demos for the GridView, you show how to populate the grid with "UnboundMode".
I've tried to reproduce the demo in my own sample project and I'm having problems. When I call RadGridView1.Items.Add(myObject), I'm getting the following exception:
"Attempt by method 'Telerik.Windows.Data.enumerableExtensions.CastTofirstElementType (System.Collections.IEnumerable)' to access method 'System.Linq.Enumerable.Cast<RadGridUnboundTest.MainPage+MyObject>(System.Collections.IEnumerable)' failed."
Can someone give me a working example of how to work with the GridView and unbound data?
