How to: Bind an Adorner to an Element

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

Example

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

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.)
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));

myAdornerLayer = AdornerLayer.GetAdornerLayer(myTextBox)
myAdornerLayer.Add(New SimpleCircleAdorner(myTextBox))

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