Public Property WindowWidth As Double

Property Value

Double

The width of a window that directly hosts a Page.

Examples

The following example shows how to set the width of a window from a page.

<Page
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="SetWindowWidthPage"
    WindowWidth="500"
    >
</Page>

Remarks

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

If a Page is hosted by a Frame, setting WindowWidth has no effect, but 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 the browser; the width cannot be changed by setting Width, MinWidth, or MaxWidth.

For more information about XBAP support, see Frequently asked questions about WPF browser-hosted applications (XBAP).

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.
