Hello,

Which one do you mean by "grouping pane"? Is it the box of group at the top? 
If yes, open xaml in Expression Blend. Right UXGridView>>Edit Additional Templates>>EditGroupByBoxStyle. In the Border>> TextBlock, simply change the text into your friendly name.

The actual names of the group descriptors are stored differently then I display as my header. This is because of the way the data is loaded.

I need to change the AppYear, AppTypeDescription, EEAckknoledged lables.  During the column generation I roll through the onGeneratingColumn event and change the header so it is a friendly name.  I need to do the same with the group lables in the grouping pane.

Hi,

Thank you for the detail. I would need to discuss this scenario with our developer teams.
