UIElement3D::OnVisualParentChanged Method

Invoked when the parent element of this UIElement3D reports a change to its underlying visual parent.

Namespace:  System.Windows
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.

OnVisualParentChanged is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.

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 UIElement3D implementation of OnVisualParentChanged, and Window seals it.
