RadControls for WPF Q3 2009.
I have predefined GroupDescriptors in XAML on the RadGrid, to show a Particular Group at start.
However the AggregateFunctions do not show up on the Group Footers or Headers.  The Group Footers also look broken, as some grid lines are missing.
In the UI, if a user removes the prefined GroupDescriptor, and creates a new group through the UI with the same Column, the AggregateFunctions do show up.

I have also attempted to do this through C#, and get the same results.
Is there a particular way of predefining the GroupDescriptors so the Column's AggregateFunctions show up in the Group Footer?

Additional question.  Is there way of defining a Column AggregateFunction to only appear in the GroupFooter, and not the header without writing a new ControlTemplate for the GridViewGroupRow?

Hello Chris,

Please excuse us for the inconvenience caused.  I have analyzed the problems and most of them are being caused by a specific bug in the aggregates result list. We are already working on fixing the bug  .  The fix will be included in our very next service pack release  within two weeks. Additionally we are going to provide a way to exclude aggregates from being shown in the group header when needed.

Thank you for the detailed description! It was very helpful for us to identify the problem.  I have updated your Telerik points.
