This is an indirect bug that may not show up on the first time. Basically, I have traced a "Dispatcher.VerifyAccess" violation to the FrameworkElementExtensions class. This issue came about while my code was updating an ObservableCollection that the RadGridView.ItemsSource was bound to. Since I can't intercept the update to the RadGridView, the "Dispatcher.CheckAccess()" would have to happen in the Telerik code. So, either this check happens in the FrameworkElementExtensions class, or somewhere in the RadGridView class, say in the GridViewDataControl.OnCollectionViewCollectionChanged() method.
