Hi Telerik Team,

I'm trying to create footer which will display elements count on predefined group .Net 4 with latest release of WPF controls (2011.2.712)

I'm using code below to create predefined group descriptor and later add aggregate funtion on column to show it in footer unfortunetly this is not working.

<telerik:RadGridView x:Name="RadGridView1" ShowGroupFooters="True" AutoGenerateColumns="False" >

<telerik:RadGridView.GroupDescriptors>

<telerik:GroupDescriptor Member="Name">

<telerik:GroupDescriptor.AggregateFunctions>

<telerik:CountFunction />

</telerik:GroupDescriptor.AggregateFunctions>

</telerik:GroupDescriptor>

</telerik:RadGridView.GroupDescriptors>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Age}" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" >

<telerik:GridViewDataColumn.AggregateFunctions>

<telerik:CountFunction Caption="count:" />

</telerik:GridViewDataColumn.AggregateFunctions>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Hello Bartosz,

It seems that you have hit a known bug in RadGridView, related to the GroupDescriptors when they are defined before the columns in RadGridView. As a possible workaround you may define the GroupDescriptor after the definition of the columns, thus you will be able to see the aggregates correctly.
