Fires when navigation bars are shown.
The NavigationBarsShown event's data class is EventArgs.
A WindowsUIView has Navigation Bars invoked with a right mouse button click. These bars contain buttons that perform navigation actions ('Home', 'Overview', 'Back' and 'Close'), buttons that perform the IWindowsUIViewController.Flip and IWindowsUIViewController.Rotate methods (for SplitGroup containers only) and custom buttons (see the figure below):
Displaying and hiding these navigation bars fires the NavigationBarsShown or WindowsUIView.NavigationBarsHidden event respectively.
The NavigationBarsShown event occurs when Navigation Bars are already displayed. You can also handle the WindowsUIView.NavigationBarsShowing event that fires immediately after an end-user calls for Navigation Bars.
