Property Value

A Double value that is the width of a window that directly hosts a Page.

WindowWidth is only applied when a Page is hosted directly by a window, which includes:

  • Window

  • NavigationWindow

  • Windows Internet Explorer

If a Page is hosted by a Frame, setting WindowWidth has not effect. Although, you can still get the value of WindowWidth.

A Page in an XAML browser application (XBAP) can only use WindowWidth to change the width of Windows Internet Explorer; the width can't be changed by setting Width, MinWidth, or MaxWidth.

The minimum width of the Windows Internet Explorer window is 250 pixels. For browser-hosted pages, this means that the value of WindowWidth may not be applied if it would cause the total width of the Windows Internet Explorer window to be less than 250 pixels.

See How to: Set the Width of a Window from a Page.
