Company | Customer | Invoices
ABC | Rick | In1
ABC | Rick | In2
ABC | Rick | In3
ABC | Chris | In4
ABC | Chris | In5
CBS | Dan | In6
From the data above, if I were to group on the first 2 columns above, I would expect to see
ABC Count:2 (# of customers in company ABC)
--->Rick Count: 3 (# of invoices for customer Rick in company ABC)
--->--->Inv1
--->--->Inv2
--->--->Inv3
--->Chris Count: 2 (# of invoices for customer Chris in company ABC)
--->--->Inv4
--->--->Inv5
CBS Count: 1 (# of customers in company CBS)
--->Dan Count: 1 (# of invoices for customer Dan in company CBS)
--->--->Inv6
Instead, I am seeing that all counts are the number of invoices within the company
ABC Count:6
--->Rick Count: 6
--->--->Inv1
--->--->Inv2
--->--->Inv3
--->Chris Count: 6
ect.
Here's my xaml for the group descriptors and the group header template:
<telerik:RadGridView.GroupHeaderTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<telerik:RadButton x:Name="btnSave" Click="btnSave_Click" Tag="{Binding Group}">
<StackPanel Orientation="Vertical">
<Image Source="../images/save.jpg" Height="30" Width="30" HorizontalAlignment="Center"/>
<TextBlock TextAlignment="Center" TextWrapping="Wrap">Update</TextBlock>
</StackPanel>
</telerik:RadButton>
<TextBlock Text="{Binding Group.Key}" FontSize="14" FontWeight="Bold" TextWrapping="Wrap" VerticalAlignment="Center" Padding="5" />
</StackPanel>
</DataTemplate>
</telerik:RadGridView.GroupHeaderTemplate>
<telerik:RadGridView.GroupDescriptors>
<telerik:GroupDescriptor Member="Company">
<telerik:GroupDescriptor.AggregateFunctions>
<telerik:CountFunction Caption="Count:"/>
</telerik:GroupDescriptor.AggregateFunctions>
</telerik:GroupDescriptor>
<telerik:GroupDescriptor Member="Customer">
<telerik:GroupDescriptor.AggregateFunctions>
<telerik:CountFunction Caption="Count:"/>
</telerik:GroupDescriptor.AggregateFunctions>
</telerik:GroupDescriptor>
</telerik:RadGridView.GroupDescriptors>
