Public Property WindowStartupLocation As WindowStartupLocation

Property Value

Type: System.Windows.WindowStartupLocation

A WindowStartupLocation value that specifies the top/left position of a window when first shown. The default is Manual.

Setting WindowStartupLocation to Manual causes a window to be positioned according to its Left and Top property values. If either the Left or Top properties aren't specified, their values are determined by Windows.

Setting CenterScreen causes a window to be positioned in the center of the screen that contains the mouse cursor.

Setting WindowStartupLocation to CenterOwner causes a window to be positioned in the center of its owner window (see Owner), if specified. The owner window can be either another WPF window or a non-WPF window.

System_CAPS_noteNote

For more information about WPF windows with non-WPF windows, see WPF and Win32 Interoperation and WindowInteropHelper.

If an owner window is not specified, the position of the window is determined in the same way as if WindowStartupLocation is set to Manual.

System_CAPS_noteNote

You cannot set or get the value of this property when a window is hosted in a browser.
