[Solved] GroupDescriptions on RadGridView

[NS]

Hi,
I upgraded to Silverlight 3.0 with the latest internal build of the Telerik Silverlight 3.0 controls.
At one point in my application, I databind a RadGridView. I have the following properties in place to make a default grouping available on the grid:

<telerik2:RadGridView AutoExpandGroups="True" Grid.Column="1" x:Name="grdResults2" ColumnsWidthMode="Auto" AutoGenerateColumns="False" Width="Auto" Height="Auto" Grid.Row="1" Opacity="0" HorizontalAlignment="Stretch">
            <telerik2:RadGridView.GroupDescriptions>
                <data:RadGroupDescription PropertyName="OUInformation"  />
            </telerik2:RadGridView.GroupDescriptions>
            <telerik2:RadGridView.Columns>
...

When I run the application, I see a nested grouping in the header. OUINformation is linked to OUInformation. In 2.0 there was only one level of grouping available (as it should be)

If I debug the application I get the following information:

?grdResults2.GroupCount
2
?grdResults2.GroupDescriptions
Count = 1
    [0]: {Telerik.Windows.Data.RadGroupDescription}
?grdResults2.GroupDescriptions[0]
{Telerik.Windows.Data.RadGroupDescription}
    base {Telerik.SilverlightExtensions.PropertyGroupDescription}: {Telerik.Windows.Data.RadGroupDescription}
    AggregateFunctions: Count = 0
    DisplayContent: "OUInformation"
    InheritedAggregateFunctions: Count = 0
    SortDirection: Ascending
?grdResults2.GroupDescriptions[1]
?grdResults2.GroupDescriptors
Count = 2
    [0]: {Telerik.Windows.Data.GroupDescriptor}
    [1]: {Telerik.Windows.Data.GroupDescriptor}
?grdResults2.GroupDescriptors[0]
{Telerik.Windows.Data.GroupDescriptor}
    AggregateFunctions: Count = 0
    DisplayContent: "OUInformation"
    Member: "OUInformation"
    SortDirection: Ascending
?grdResults2.GroupDescriptors[1]
{Telerik.Windows.Data.GroupDescriptor}
    AggregateFunctions: Count = 0
    DisplayContent: "OUInformation"
    Member: "OUInformation"
    SortDirection: Ascending

Any help on this ?
Thanks,
Nicolas

It must be something freaky on my side.
If I place the following code after setting the datacontext:

grdResults2.GroupDescriptors.RemoveAt(1); then I get the expected result.

I will try to prepare a demo project.

Found the problem:
I had to change the line

 

 

<telerik2:RadGridView.GroupDescriptions>  to <telerik2:RadGridView.GroupDescriptors>
