Grouping Error after 2010.1 422 upgrade

[Paul Kleynhans]

Hi Guys,

I've upgraded to RadControls_for_Silverlight_3_2010_1_0422.
Now, if I try and group the grid by dragging a column header into the grouping block, I get the following error :

Line: 56
Error: Unhandled Error in Silverlight Application
Code: 4004   
Category: ManagedRuntimeError      
Message: System.InvalidOperationException: MeasureOverride of element 'Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel' should not return PositiveInfinity or NaN as its DesiredSize.
   at System.Windows.FrameworkElement.MeasureOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)

This worked before the upgrade.

Kind Regards
Paul

I only get this error if I navigate to a datapager tab other than the first tab and group it then.

Hello Paul,

RadGridView placed in StackPanel and/or ScrollViewer will be measured with infinity and in this case you will get serious problems with performance, etc. Why not use Grid instead?

Thank you, I replaced my Scrollviewer and Stackpanel with a Grid, this solved the error.
I am confused though, why was this working in the previous version?
I prefer working with stack panels, as it keeps the controls neat and close together easier than in a grid.
Is this a Silverlight or a Telerik issue?

[Milan]

Hi Paul Kleynhans,

Neither Silverlight nor Telerik is to blame. The problem with StackPanel is that it will measure all of its children with infinite height which renders our virtualization mechanism useless - and ultimately this manifests as poor performance and strange behavior.

All virtualization mechanisms rely on finite height/width to calculate how many UI containers should be created and if you get infinity there is no way perform this calculation.

Hope this clears the problem a bit.
