How can I override the ContextMenu on the tab headers? I want to have my own menuItems when a user right-clicks on the tab header. I've added the context menu to each of the elements, and it doesn't seem to make it available where I'd expect.
<docking:DockSite Name="m_scriptEditorDockSite" CanDocumentWindowsFloat="False"
CanDocumentWindowsDragToLinkedDockSites="False" KeyDown="OnKeyDown">
<docking:Workspace>
<docking:TabbedMdiHost AllowDrop="False">
<docking:TabbedMdiContainer>
</docking:TabbedMdiContainer>
</docking:TabbedMdiHost>
</docking:Workspace>
</docking:DockSite>
