RadGridView - GroupDescriptor resetted after regrouping

[Victor]

Hello,

We have definition of RadGridView with a GroupDescriptor:

<TelerikControls:RadGridView Name="grid" SelectionMode="Multiple" IsReadOnly="True">
   <TelerikControls:RadGridView.GroupDescriptors>
      <telerik:GroupDescriptor Member="Id" SortDirection="Ascending">
         <telerik:GroupDescriptor.AggregateFunctions>
            <telerik:CountFunction Caption="Models: " />
            <telerik:SumFunction Caption="Reslts: " SourceField="ResultCount" />
         </telerik:GroupDescriptor.AggregateFunctions>
      </telerik:GroupDescriptor>
   </TelerikControls:RadGridView.GroupDescriptors>
</TelerikControls:RadGridView>

If the user un-groups the grid and then groups it by "Id" over again,
information in the group header gets lost. Is it a bug?

Thank you,
Victor

Hello Victor,

Tthat's expected. The user removes the original descriptor that had the aggregates and then adds a new one -- that does not have them.

You can try to add these aggregates on the fkly by attaching to the Grouping event of RadGridView. There you will have access to the GroupDescirptor that will be added.
