Hello,

I  am using xamDataGrid with the Theme "Aero". I  tried to change the Background of GroupByAreaMulti, but i can not change all background. How can i change the blue line? Or is there a Template for GroupByAreaMulti?

MY XAML (xamDataGrid):

<igDP:XamDataGrid Theme="Aero"  BindToSampleData="True" Name="xamDataGrid1" IsGroupByAreaExpanded="True">
        <igDP:XamDataGrid.GroupByAreaMulti>
                <igDP:GroupByAreaMulti  IsExpanded="True" Background="Gray" />
       </igDP:XamDataGrid.GroupByAreaMulti>
</igDP:XamDataGrid>

Thank you!
