UIElement::OnVisualParentChanged Method
Visual Studio 2010
Invoked when the parent element of this UIElement reports a change to its underlying visual parent.
Assembly: PresentationCore (in PresentationCore.dll)
protected public: virtual void OnVisualParentChanged( DependencyObject^ oldParent ) override
Parameters
- oldParent
- Type: System.Windows::DependencyObject
The previous parent. This may be provided as nullptr 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.
