    Syntax
    protected internal virtual void OnPaneClosing( 
       Pane pane,
       CancelRoutedEventArgs e
    )
    Protected Friend Overridable Sub OnPaneClosing( _
       ByVal pane As Pane, _
       ByVal e As CancelRoutedEventArgs _
    ) 

    Parameters

    pane
    The Pane being closed.
    e
    The event data associated with the closing event. Set the Cancel property to false to cancel the action.
    Remarks
    Modules are automatically notified whenever one of its panes are activated, deactivated, opened, or closed. This means a Module doesn’t have to listen to the Framework’s ActivePaneChanged event and from here filter for its panes; instead, Modules are given direct notification that one of their panes changed.
    Requirements
