Removing the default text in Xceed datagrid

wpf, wpfdatagrid, xceed, xceed-datagrid

Solution

I tried this. It worked.

 <Style TargetType="{x:Type xcdg:HierarchicalGroupByControl}">
            <Setter Property="Visibility" Value="Collapsed"/>
        </Style>

Problem

I am using the Codeplex verison of Xceed datagrid. But while showing the grid in form, 'Powered by Xceed' text is coming in top right of datagrid. Is it possible to remove this? How?
