ContentElement.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 virtual 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. FrameworkContentElement 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.
