Hi,
If set a GroupDescriptor from XAML (or C#), the group descriptor is collapsed. (see screenshot)

    
             <telerikGridView:RadGridView.GroupDescriptors> 
        
                                <data:GroupDescriptor Member="oArticleCategory.oArticleType.Description">  
        
                                </data:GroupDescriptor> 
        
                            </telerikGridView:RadGridView.GroupDescriptors>

Is it possible to expand the records on the groupdescriptor by default ?

Thanks,
Nicolas

Hello,

In Silverlight 4 this cannot be achieved with simple style for the GridViewGroupRow since there are no bindings in the setters - you can simply set true or false:
<Grid.Resources>
   <Style TargetType="telerik:GridViewGroupRow">
   <Setter Property="IsExpanded" Value="True" />
   </Style>
   </Grid.Resources>

In Silverlight 5 this will be possible.

To achieve your goal with Silverlight 4 you will need to redefine the GridViewGroupRow template with Blend and attach your converter to the IsExpanded binding(s).
