Expand GroupDescriptor

[NS]

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 NS,

Please set the AutoExpandGroups property of RadGridView to true.

All the best,

Is it possible to expand/collapse each group via a converter in the xaml (MVVM)?

thanks.

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).
