Adorner Class

Abstract class that represents a FrameworkElement that decorates a UIElement.

Namespace: System.Windows.Documents
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:

public abstract class Adorner : FrameworkElement

public abstract class Adorner extends FrameworkElement
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

An adorner is a custom FrameworkElement that is bound to a UIElement. Adorners are rendered in an adorner layer, which is a rendering surface that is always on top of the adorned element or a collection of adorned elements; rendering of an adorner is independent from rendering of the UIElement that the adorner is bound to. An adorner is typically positioned relative to the element to which it is bound, using the standard 2-D coordinate origin located at the upper-left of the adorned element.


The parent of an Adorner is the AdornerLayer that renders the Adorner, not the element being adorned.


Anything placed in the adorner layer is rendered on top of the rest of any styles you have set. In other words, adorners are always visually on top and cannot be overridden using z-order.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
