UIElement.OnVisualParentChanged Method

Invoked when the parent element of this UIElement reports a change to its underlying visual parent.

Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)
protected internal override void OnVisualParentChanged(
	DependencyObject oldParent
)

Parameters

oldParent
Type: System.Windows.DependencyObject
The previous parent. This may be provided as null if the DependencyObject did not have a parent element previously.

Notes to Inheritors

If you override this method, always call the base implementation. The default base implementation performs some internal maintenance of reverse-inherited property state. Failing to call the base implementation will invalidate this state.

This method overrides Visual.OnVisualParentChanged. FrameworkElement and Window both also override the UIElement implementation of OnVisualParentChanged, and Window seals it.
