  • Reference

Definition

Namespace:
System.Windows
Assembly:
PresentationCore.dll

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

protected public:
 virtual System::Windows::DependencyObject ^ GetUIParentCore();
protected internal virtual System.Windows.DependencyObject GetUIParentCore ();
abstract member GetUIParentCore : unit -> System.Windows.DependencyObject
override this.GetUIParentCore : unit -> System.Windows.DependencyObject
Protected Friend Overridable Function GetUIParentCore () As DependencyObject

Returns

DependencyObject

An object, if implementation of a derived class has an alternate parent connection to report.

Remarks

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.
