Constrained Docking Direction

Does anyone know of a way to restrict a pane from docking to the top and bottom of the main frame... but still be able to dock anywhere on another docking pane??

private void DockingPane_Action(object sender, AxXtremeDockingPane._DDockingPaneEvents_ActionEvent e)

{

    switch (e.action)

    {

        case DockingPaneAction.PaneActionDocking:

            if ((e.container.Direction == DockingDirection.DockTopOf || e.container.Direction == DockingDirection.DockBottomOf) &&

                (e.container.Container.Type == DockingPaneType.PaneTypeClient || e.container.Container.Type == DockingPaneType.PaneTypeSplitterContainer))

                e.cancel = true;

            break; 

    }

}
