Hello,

I have a difficulty about binding a list of type Binding<T> list to Grid. The binding is working fine, but grouping is not working on the side of XAML.

<Telerik:RadGridView.GroupDescriptors> 
                <data:GroupDescriptor Member="CodeOrganizationType">  
                    <data:GroupDescriptor.AggregateFunctions> 
                        <data:CountFunction Caption="Count:" /> 
                    </data:GroupDescriptor.AggregateFunctions> 
                </data:GroupDescriptor> 
            </Telerik:RadGridView.GroupDescriptors> 

grouping via code works fine, XAML is not working.

Am I doing something wrong ?

Telerik Version : 2010.1.0422.35
VS2010, .NET 3.5 & 4.0

Please help...

Hi dogu.tumerdem, 

As I understand you are using BindingList<T> as ItemsSource for the RadGridView. I have been investigated the reported behavior and found an issue with group aggregates when grid is bound to ICollectionView. We are currently working on solution which will be available in one of our next internal build. You can track issue project in our Pits System - http://www.telerik.com/support/pits.aspx#/public/wpf/2306

Thank you for reporting this issue - I have updated your telerik point accordingly.

Please excuse us for any inconvenience caused.

Kind regards,

Dear Colleague,

In SP2 (2010.1.0603.35), Groups are visible now, not aggregates...
Thank you,

Hello dogu.tumerdem,

Unfortunately, The fix for this issue didn't make it in the SP2 release. It will be included in the next internal builds and the upcoming beta release.
