Expanding group in RadGridView hangs reproducible

[Nico Just]

Hi,

I noticed, that under cetain circumstances my whole application hangs when trying to expand a group in the RadGridView. To reproduce, please find the example app here:

https://dl.dropbox.com/u/1551828/WpfApplication1.zip

and follow the steps described below:

1. Expand the groups 5-1 (in that order)
2. Maximize the window
3. Collapse the groups 1-5 (in that order)
4. Epand the group 5
5. The App hangs in:

Telerik.Windows.Controls.GridView.dll!Telerik.Windows.Controls.GridView.GridViewCellsPanel.UpdateVirtualizedCells() Line 269    C#
Telerik.Windows.Controls.GridView.dll!Telerik.Windows.Controls.GridView.GridViewCellsPanel.MeasureOverride(System.Windows.Size availableSize) Line 306  C#

The version of the Telerik WPF UI Controls is: 2012.2.912.35. Client OS is Windows 7 x64.

Hello,

I have tested your solution with our just released Q3 2012. With it we have introduced new grouping mode which can be used by setting the GroupRenderMode="Flat". Please upgrade and set this new property.

I hope this resolved your grouping problems.

Hi,

thanks, the GroupRenderMode="Flat" solves that issue. Are there any plans to have fix for this in a WPF35 version?

Kind Regards,
Nico

Hi,

 GroupRenderMode="Flat" is available for both 3.5 and 4.0 versions of our assembly. 

Kind regards,

Hi,

I've downloaded the 2012.3 1017 release.There is no version 3.5 included, only 4.0 and 4.5. Is there something I'm missing?

Kind Regards,
Nico

Hello,

Actually with Q3 2012 we have discontinued the support for WPF 3.5, please check this announce. This property is available for 4.0 and 4.5 versions of our assembly.

I would suggest you to upgrade to a newer version.
