GridViewSelectColumn White Screen of Death

[Brian Sayatovic]

I have a RadTabControl and in my first tab, part of my content is a RadGridView with a GridViewSelectColumn.  The default header checkbox works great.  I can toggle it several times without an issue.

However when I switch to another tab and then attempt to switch back, my browser windows gets the "white screen of death" (the entire Silverlight control goes white and the only resort is to start over entirely).

Oddly, if we specify a header for the GridViewSelectColumn of a single space (Header=" "), then the problem doesn't occur -- and the select-all checkbox in the header is of course gone.

Any ideas?

While attached, I managed to catch the JavaScript-level wrapper of the underlying exception (I think):

Hi,

 I have tested the scenario described by you, but I couldn't get any problems on switching the tab items. I have tested with the binaries from the Q3 Service Pack. Would you please confirm the version of the RadControls that you use?

Hello,

 This is our Q2 2011 SP1. Please upgrade to our latest official version - Q3 2011 SP1.

I'm trying to upgrade to Q3 2011 SP1, but so far I've encountered backwards-breaking changes:

• DataTemplateSelector no longer extends DependencyObject
• Fatal error complaining the property 'IsHeaderHitTestVisible' was not found in type 'Telerik.Windows.Controls.RadWindow' (see http://www.telerik.com/community/forums/silverlight/window/new-error-after-upgrading-2011-q2-to-q3-isheaderhittestvisible-not-found.aspx)

If I can get past these issues, I'll let you know if the upgrade solves my original problem.

After getting past those two issues, the GridViewSelectColumn is now NOT crashing my screen!
