Hello,
I ran into several issues related to vertical scrolling of a (XAML) RadDataGrid that shows grouped content.
I've prepared a sample project with which the issues can be consistently reproduced, but I am not sure how it can be posted because of the limitations that the forum imposes on the allowed file types. Please advise how I can send it to you.
The 2 screenshots attached illustrate the issues I am going to describe.
Issues #1 to #3 occur with both Telerik Controls v.2013.2.625 and v.2013.2.716:
1. If all the groups are collapsed by default (which is the case in the sample), the vertical scroll bar still appears - even though there is plenty of space for the collapsed group headers to fit into the page's height without scrolling.
2. It is possible to scroll down do that the collapsed group headers disappear beyond the top edge of the page altogether. When the scroll bar gets hidden after a short period of user's inactivity, the user is left with an empty screen.
3. Vertical scroll bar's behaviour is inconsistent: if I expand and collapse back all the groups, the scroll bar will eventually disappear (which implies the recalculations happening upon these events eventually yield the right result - but not from the beginning).
Issue #4 occurs only with Telerik Controls v.2013.2.716:
4. If I expand the first group, scroll down to the bottom, and then collapse the group back, the header for that group is replaced with the header for another group (in the attached screenshot you can see the "List 1" was replaced with "List 3"). If I tap to expand that first list again, the other one (whose "identity" has got borrowed to substitute the first one) becomes expanded. After that, the first list "gets its identity back".
Please have these issues addressed in the next release of the controls.
Thank you.

Hi Yuri,
Thank you for reporting these issues and providing detailed information regarding the steps to reproduce. Issues 1-3 are known and we have addressed them in our most recent internal build (ver. 2013.2.806).
While we were unable to reproduce issue 4 we believe it is related to the other ones. So, I can encourage you to try our internal build and let us know if you experience the same issue using it. If this is the case, you can open support ticket and attach a project that reproduce the issue, so we can isolate it and address it for the next official release.
Regards,

It would appear like the issue #4 is also resolved in the internal build 2013.2.806.
