RadGridView in WindowsForms ElementHost

[Boots]

Hello,

Recently we updated the Telerik assemblies in our product to 2012.3.1017.40 and we've encountered an issue. When the user drags a column header to the group panel they encounter a NullReferenceException. We're hosting the control in a Windows Forms ElementHost control.

Any ideas on a workaround would be very helpful.

Stack Trace:
   at Telerik.Windows.Controls.DraggedElement.HideNoCursor()
   at Telerik.Windows.Controls.GridView.DragDropController.OnGroupPanelDragOver(Object sender, DragEventArgs e)
   at System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target)

Let me know if you need any more information. 

Thanks Much,

Hi Ben,

The exception should be fixed with our latest official binaries - Q3 2012 SP1. Could you give it a try and let me know if you find any problems?
