Namespace:  System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

member SizeToContent : SizeToContent with get, set
<object SizeToContent="SizeToContent" .../>

Property Value

Type: System.Windows.SizeToContent
A SizeToContent value. The default is Manual.

Identifier field

SizeToContentProperty

Metadata properties set to true

None

When SizeToContent is set to WidthAndHeight, setting either Height or Width has no effect; both properties can be set, but the values they are set with are not applied to the window.

When SizeToContent is set to Height, setting Height does not change the height of the window.

When SizeToContent is set to Width, setting Width does not change the width of the window.

If SizeToContent has a value other than Manual:

  • SizeToContent is automatically set to Manual if a user resizes the window by using the resize grip or dragging the border.

  • If the size of the content changes in a way that causes the window to resize itself, SizeChanged is raised.

If a window is transparent (see AllowsTransparency), you should consider setting SizeToContent to WidthAndHeight to ensure the window is no larger than its visible content.

NoteNote

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

The following example shows how to set the SizeToContent property in code to specify how a window resizes to fit its content.
