Hello.  My grid totals each column and has a group summary.  I can't seem to get rid of the column totals in the group.

The attached image shows what I'm trying to remove.

Thank you.

Hi,

 You can use ShowHeaderAggregates property of GridViewGroupRow. Here is an example:

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

Thank you.  I'd like to keep the total allocated and remove the Jan-Dec column "sums" as shown in the uploaded image.

Is this possible?  My Q3 2009 XAML worked perfectly but Q1 and Q1 SP2 do not so I'm trying to figure out how to make it work.  In Q3, I simply had the following footer.  It did not render group column totals by default.

<telerikGridView:GridViewDataColumn.Footer > 
                                            <Telerik_Windows_Controls_GridView:AggregateResultsList ItemsSource="{Binding}" HorizontalAlignment="Right" VerticalAlignment="Center"
                                                <Telerik_Windows_Controls_GridView:AggregateResultsList.ItemTemplate> 
                                                    <DataTemplate> 
                                                        <StackPanel Orientation="Horizontal" VerticalAlignment="Center" Height="40"
                                                            <TextBlock VerticalAlignment="Center" TextAlignment="Right" FontSize="11" x:Name="txtJanFtr" FontWeight="Bold" Text="{Binding FormattedValue}" />                                                
                                                        </StackPanel> 
                                                    </DataTemplate> 
                                                </Telerik_Windows_Controls_GridView:AggregateResultsList.ItemTemplate> 
                                                <Telerik_Windows_Controls_GridView:AggregateResultsList.ItemsPanel> 
                                                    <ItemsPanelTemplate> 
                                                        <StackPanel Orientation="Vertical" /> 
                                                    </ItemsPanelTemplate> 
                                                </Telerik_Windows_Controls_GridView:AggregateResultsList.ItemsPanel> 
                                            </Telerik_Windows_Controls_GridView:AggregateResultsList> 
                                        </telerikGridView:GridViewDataColumn.Footer>

Hi John Morris,

You can get the old behavior by adding the GroupDescriptor programatically. You can try something like this:

private bool loaded = false;
  
// subscribe to DataLoaded event
void clubsGrid_DataLoaded(object sender, EventArgs e)
{
    if (loaded)
        return;
  
    this.loaded = true;
  
    GroupDescriptor desctiptor = new GroupDescriptor();
    desctiptor.Member = "Number";
    desctiptor.AggregateFunctions.Add(new MaxFunction() { SourceField = "Number" });
  
    this.clubsGrid.GroupDescriptors.Add(desctiptor);
}
