AdornerLayer.Add Method

Adds an adorner to the adorner layer.

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

public void Add(
	Adorner adorner
)

Parameters

adorner
Type: System.Windows.Documents.Adorner
The adorner to add.

ExceptionCondition

Raised when adorner is null.

This example shows how to programmatically bind an adorner to a specified UIElement.

To bind an adorner to a particular UIElement, follow these steps:

 

  1. Call the static method GetAdornerLayer to get an AdornerLayer object for the UIElement to be adorned. GetAdornerLayer walks up the visual tree, starting at the specified UIElement, and returns the first adorner layer it finds. (If no adorner layers are found, the method returns null.)

  2. Call the Add method to bind the adorner to the target UIElement.

The following example binds a SimpleCircleAdorner (shown above) to a TextBox named myTextBox.


myAdornerLayer = AdornerLayer.GetAdornerLayer(myTextBox);
myAdornerLayer.Add(new SimpleCircleAdorner(myTextBox));


NoteNote

Using Extensible Application Markup Language (XAML) to bind an adorner to another element is currently not supported.
