[Solved] GroupHeaderDisplayMode doesn't seem to have any effect

[Yuri]

Hello,

I have encountered this issue after updating Telerik Controls to the latest public release (2013.3.1015).
Before the update, group headers would remain "frozen" at the top of the view when a long grouped GridView is scrolled.
After the update, the group headers are scrolled out of the view together with the top of their child content.
I found that there now is the GroupHeaderDisplayMode property to manage this, but any attempts to apply it appear to have 0 effect on the UI behavior.
I tied setting GroupHeaderDisplayMode="Frozen" on the GridView in XAML, as well as grid.GroupHeaderDisplayMode = DataGridGroupHeaderDisplayMode.Frozen;

Is there an issue, or am I missing some important point?

Thank you

P.S. This is with Windows 8.1 Preview, over .NET for Windows Store apps v4.5.1

Hi Yuri,

Thank you for contacting us and for your question.

We did some performance optimizations and refactoring on the Virtualization logic in the Grid and unfortunately this refactoring introduced the bug you describe.

We are preparing a native 8.1 build of our components that should be ready by the end of the next week and we will push the fix of this bug to the 8.0 and 8.1 versions of our tools.

I would like to thank you for your feedback and for bringing this issue to our attention - I have updated your Telerik points as a token of gratitude. Do not hesitate to write us back should you have any other issue/problem with our components.

Regards,
Georgi

Any news on this subject? Is the new release ready yet?

Hi Yuri,

Unfortunately, the preparation of the component builds proved to be a little more time consuming than we have initially estimated. The Q3 2013 SP1 version should be released by the end of this week.

We apologize for the delay and any inconvenience this may have caused.

Regards,
