Memory leak with RadTreeView

[James]

Hi,

When I changed my RadTreeView to multiselect mode I found that unless I cleared the selection before removing nodes from the tree it held onto references to the classes it was bound to. I used WinDbg to look at the memory, below is the end of the !gcroot showing the path to a class that should be ready for garbage collection. I think the suspicious line is "059d7dd0(Telerik.Windows.Controls.SelectionChanger`1[[System.Object, mscorlib]])->".

Are you aware of any such issues with the RadTreeView in the Q3 2010 release?

Any info appreciated,

Cheers,

James Clarke

Hello James,

We are aware that in some cases the selected items collection is not updated. However I couldn't find that issue in the public issue tracking system so I logged it. You can vote for the fix and track its status via this link: http://www.telerik.com/support/pits.aspx#/public/silverlight/4586 .

Also, I updated your Telerik points (+1000).

Regards,
