I'm using Silverlight 3 Q3 beta. But it is not depend to latest release.

It is rather hard to create example that reproduce problem.

I have binded RadGridView to Children (Data items not RadTreeViewItems) of selected TreeViewItem.

For root children it works okey, but while we selecting other nodes that cause rebind of RadGridView multiselect stop working. But single selection is still work okey.

Hi Alexey,

This bug has been fixed but the fix will only be available (this Friday) with our latest internal build for Q2 2009 SP1. Unfortunately we cannot provide internal builds for our beta releases.

Kind regards,
