[Solved] GridView inside RadWindow resize issue

[Jeremy]

I have an issue with a GridView User Control as the content (with alignments set to Stretch) within a RadWindow.  When I resize the window enough to cover the data rows in the Grid the web browser locks up and I cannot continue within the current session.  This occurs in both IE 6 and FireFox.

I was able to write a couple sample xamls to illustrate the issue I am having.  After you open the new window and resize the window smaller (towards as small as it can go) the browser will hang. 

Following are the sample xaml snippets. 
Thank you for your help.

Hello Jeremy,

Thank you for the feedback. I still investigate what happens when the RadGridView is resized to a very small size, but I need to research this further.

Probably, this is a bug in the RadGridView control.

I'll give you additional information as soon as possible.

Kind regards,

I am currently referencing the new futures build that was released (RadControls for Silverlight 2008 3 1217 Futures).  This release did seem to fix this issue for some instances. However if I am resizing and moving the window around the browser the issue does seem to still occur at times.  Unfortunately the way to reproduce the problem isn't as consistent as before.

I still seem to be able to recreate the issue with the code sample in the previous posting.  It is mostly just moving the window and resizing the window (using the corner resize) that seems to generate the issue.

Are you aware of any work arounds for this issue until it has been resolved?

If I can provide any other information about this issue please let me know and I'll do my best to do so.
Thank you for your help.
