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
)
protected void OnVisualParentChanged (
	DependencyObject oldParent
)
protected internal override function OnVisualParentChanged (
	oldParent : DependencyObject
)
You cannot use methods in XAML.

Parameters

oldParent

The previous parent. This may be provided as a null reference (Nothing in Visual Basic) 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.
