Show/Hide System Tray in applications

To display system tray in XAML page of your application you have to add the following line of code to <phone:PhoneApplicationPage> element (note that by default this attribute is set to True):

 
shell:SystemTray.IsVisible="True"

To hide system tray in your XAML page you have to set this attribute to False (it will add some additional room for the content of your application page):

 
shell:SystemTray.IsVisible="False"
