All of the values in my Group Footers row show in the Group Headers row.  I would like to hide most of the values and show only 2.  How can I selectively show some values in the Group Header and hide others?

Thank you.

Hello,

 You could predefine the GroupHeaderTemplate for the columns on which you would like to change the shown aggregate values. What I can suggest you is to check the approach shown on this online demo and apply it to your particular scenario.

Can you tell me how I define the GroupHeaderTemplate so that it's hidden?  I tried the code below, but it did not work.  Could that be because I'm skinning the gridview?

<telerik:GridViewDataColumn.GroupHeaderTemplate>
     <DataTemplate>
          <TextBlock Text="{Binding Group.Key}" Visibility="Hidden"/>
     </DataTemplate>
</telerik:GridViewDataColumn.GroupHeaderTemplate>

Hi,

 I have checked the demo and there is something missing there. You should hide the header aggregates for the GridViewGroupRow:

<telerik:RadGridView.GroupRowStyle>
   <Style TargetType="telerik:GridViewGroupRow">
         <Setter Property="ShowHeaderAggregates" Value="False"></Setter>
      </Style>
</telerik:RadGridView.GroupRowStyle>

Then you should be able to  hide the group aggregates for some columns.

When I do this, it hides ALL of the aggregate headers.  How do I add some of them back while keeping others hidden?

Thank you.

Hi,

 You are right. After you set the ShowHeaderAggregates, then the header aggregates will not be shown any more.
You should define a GroupHeaderTemplate for each column where you would like to show the aggregated value back.

I'm using the method you describe above to hide the header and the following code to add headers back

<telerik:GridViewDataColumn.GroupHeaderTemplate
     <DataTemplate
          <TextBlock Text="{Binding Group.Key}"
     </DataTemplate
</telerik:GridViewDataColumn.GroupHeaderTemplate>

This is not working for me.  I still get no headers at all.  Can you tell me what I'm doing wrong?

Hi,

So you would like to hide some aggregate results (not just group headers) in the group header and show other. Please excuse me for this misunderstanding. 

You cannot just hide some of them, but I have prepared a sample project on how you could remove the AggregateResults you do not like to be shown.

Please find it attached for a reference.

All the best,
