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.
