UIElement3D.GetUIParentCore Method

When overridden in a derived class, returns an alternative user interface (UI) parent for this element if no visual parent exists.

Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

protected internal DependencyObject GetUIParentCore()

Return Value

Type: System.Windows.DependencyObject
An object, if implementation of a derived class has an alternate parent connection to report.

The default virtual implementation of this method returns null. FrameworkElement provides a practical implementation.

Alternative parents are used for event routing, in cases where an element creates an alternative parent structure so that its events are routed in a way that diverges from the standard pattern of routing up the visual tree to the standard parent, or downward in the preview routing strategy.

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