Hi,
In the application we're building we use the RadGridView (version 2009.2.701.35) in an UserControl that is added to a TabControl as the content of a TabItem.
When the TabItem containing the RadGridView is removed from the TabControl (=closed), the application still holds a reference to the UserControl. We've tried everything, including memory profiling. If we replace the RadGridView with a standard WPF ListView on the UserControl, the reference to the UserControl no longer exists!
To reproduce this in a more simple environment, we created a new WPF application containing 2 Windows. The startup window contains 1 button, doing nothing more then showing the 2nd window. The 2nd window contains a RadGridView, and in the constructor of the window the RadGridView is filled with 300.000 items.
Memory profiling that test application shows that after closing the 2nd window, there is still a reference to it, while if we replace the RadGridView with a standard WPF ListView again, there is no reference.
Is there something we're missing or is this a (serious) bug in the RadGridView? I can't find anything in the release notes newer then the version we use that this is already fixed, nor can I find anything on the forums about a memory leak...

Hi Vlad,
Thanks for the fast response!
And Zai, thanks for saving me the trouble of having to test 2 versions :)
Just now, I tested it with the latest internal build (2009.2.925.35), and the problem still exists.

Just tested this again in the latest internal build (2009.2.1002.35), and I no longer see it occur! Great job!
When is the next release scheduled? Can't wait to get this fix :)
