ApplicationBar.Opacity Property
July 26, 2012
Gets or sets the opacity of the Application Bar.
Assembly: Microsoft.Phone (in Microsoft.Phone.dll)
XMLNS for XAML: Not mapped to an xmlns.
Expected values are between 0.0 and 1.0. A value of 0.0 makes the Application Bar completely transparent, while a value of 1.0 makes the Application Bar completely opaque. The default value is 1.0.
If the opacity of the Application Bar is set to 1.0, the currently displayed page is resized to the area of the screen not occupied by the Application Bar. If the opacity value is less than 1.0, the Application Bar is overlaid over the contents of the page, and the page is not resized.
