RadPaneGroup DropDownMenu only on first group

[Steve]

If I have document panes in two RadPaneGroups, the dropdown list of open documents is only shown in the first group.  Is this by design? And if so would it be possible to have it displayed in all groups? I've attached an image illustrating the current problem.
Thanks in advance,
Steve

Hello Steve,

When you drag a PaneGroup in the DocumentHost new PaneGroup is generated and by default its DropDown is not visible. So in order to overcome that you need to apply an implicit style in App.xaml:

<Application.Resources>
        <Style x:Name="paneGroupStyle" TargetType="{x:Type telerik:RadPaneGroup}">
            <Setter Property="DropDownDisplayMode" Value="Visible"/>
        </Style>
    </Application.Resources>

You can find a simple implementation in the attached project .
Hope this will help.

Kind regards,
Georgi
