Group Header Template

[Koren]

I have a data entry grid that I am grouping by a code in each detail record (by default - the user does not see the grouping panel).  I would like to be able to show some additional data from the group on the header.  To do this I am using Aggregate functions which does display the correct data.  However, I really want to be able to format these results to save some space and make the display more readable.  For example:
00000 Description   Cash  Inv
                                1.00   5.00

What shows is:
00000 Description  Cash 1.00  Inv 5.00

If I leave the aggregate functions showing, I can't seem to format them.  Here is the group descriptor and template that I am trying to use.  What am I missing?  Is there another way to do this?  The data is really parent/child related but the data entry is better for our users if they can go from one "parent' to another so flattened the heirarchy.  This is working fine except the display of the group header.

thanks, Koren
P.S. I realize that the template display may not be exactly right but I can't tweak it until it actually displays something.

<telerik:RadGridView.GroupHeaderTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal" Margin="0,0">
                        <TextBlock Text="{Binding Group.Key}" Margin="0,0,0,2" Width="200" />
                        <telerik:AggregateResultsList ItemsSource="{Binding}" VerticalAlignment="Center">
                            <ItemsControl.ItemTemplate>
                                <DataTemplate>
                                    <StackPanel Orientation="Vertical" VerticalAlignment="Center">
                                        <TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="{Binding Caption}" Width="80" />
                                        <TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="{Binding FormattedValue}" Width="80" />
                                    </StackPanel>
                                </DataTemplate>

Hello Koren,

You have missed to specify the correct binding for the AggregateResultsList

...<telerik:AggregateResultsList ItemsSource="{Binding AggregateResults}" VerticalAlignment="Center">

<ItemsControl.ItemTemplate>

    <DataTemplate>

  <StackPanel Orientation="Vertical" VerticalAlignment="Center">

 <TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="{Binding Caption}" Width="80" />     <TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" Text="{Binding FormattedValue}" Width="80" />

</StackPanel>

</DataTemplate>

...
</telerik:AggregateResultsList>

Furthermore, you need to hide the default group header. You could do it like so: 

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

I hope that this is helpful and your problem will be resolved.

 Please try this and share with me how it works.
