Assembly: PresentationCore (in presentationcore.dll)
Typically, updates and notifications happen automatically after the update of the layout in Windows Presentation Foundation (WPF). (The update occurs in response to the LayoutUpdated event.) Sometimes, however, properties change without raising the LayoutUpdated event. For example, when the whole Window moves, the LayoutUpdated event is not raised. In this example, the set of BoundingRectangle objects change because the objects are expressed in screen coordinates. Therefore, the Window must call InvalidatePeer on its peer on WindowAutomationPeer.
