1. Set RadGridView's setting DragElementAction="ExtendedSelect". 
2. Open a window on selecting a row.
3. Close the window, the RadGridView becomes ExtendedSelect.

Note: Most probably this problem is actually caused by a limitation in the Silverlight platform. Once a Window is shown, there is no way to detect that the mouse is released.

Scrolling performance is degraded when RowStyle/RowStyleSelector that sets Template property is explicitly applied

'Cell is already in the collection' exception is thrown when multiple cells are copied and pasted in a sorted column

Hello Telerik  Team!

Are there any new informations concerning the below BUG?
(UniqueName-Property is causing binding errors) 
Is this fixed in one of the current versions? What are proper workarounds?

Identical Problem for Sylverlight:
