Intermittent problem with blank areas between groups after scrolling back

[Imran Javed Zia]

Hi,
We had a List page in which Shows a list of items in RadGrid, It works fine but when we scroll down and back to up then different blank areas are visible in grid area. We are using 2011.2.920.40 version of WPF controls.

I have attached screen shots before and after scrolling back.
Thanks

Hi,

 We have done several improvements on scrolling in grouped scenario after the version you use (2011.2.920). May I ask you to upgrade to the latest version (Q2 2012 SP - 2012.2.725) and let me know if you still get empty areas?

Unfortunately, we are in critical phase of our application and cannot update controls yet. But if you confirm me it is a but and has been fixed in new release then we may try to plan to upgrade to newer version.

Hello,

 We have address most of the cases, but it is possible that in some scenario the problem is still observed. You could be sure after you test this particular application using the latest binaries.

Kind regards,
