Telerik Gridview having a Column with TOOLTIP Shown

[Jeffrey]

When scroll up and down the RadGridView which has a tooltip on one GridViewColumn, the whole silverlight application will crash.

IMPACT:

1. Silverlight application crash and data lost.
2. Because we need to export the GridView to excel and won't like to use Paged-GridView, it's really a blocking issue for us.

TELERIK VERSION:

2011.1.419.1040

REPRO STEPS:

1. Wrote a sample VS solution for repro.  See attached TelerikGridViewBUG.zip for detail.
2. Open Visual Studio solution TelerikGridViewBUG.sln with admin privilege.
3. Click through Visual Studio menu Debug -> Exceptions to launch the Exceptions dialog.
4. Check "Common Language Runtime Exceptions" checkbox on the Exceptions dialog and click OK to save.
5. Press F5 to launch the website in debugger mode and click the "Show Question" button on the page
6. On the launched "RadGridViewChildWindow", use Mouse to scroll down once. See the illustration below. See Illustration3 for detail.
7. Use mouse to scroll up to the top of the RadGridView.
8. Mouse hover on the "Question Description" column of the RadGridView.  You should choose the other row of the current Mouse located at.
For example, after you scroll up to the top of the RadGridView, your mouse are at row 4. Then try to move your mouse to row 2 and column "Question Description" to let the tooltip shown.
See Illustration4 for detail.

9. KEEP THE TOOLTIP SHOWN MORE THAN 2 SECONDS AND QUICKLY SCROLL DOWN.
10. You will see the Silverlight Application crash.

Would you please let me know how to attach my project zip to you? Or I could send it to you?  It's about 1.3Mega bytes.
