How to: Remove an Adorner from an Element
This example shows how to programmatically remove a specific adorner from a specified xref:System.Windows.UIElement.
Retrieve an adorner on a UIElement
This verbose code example removes the first adorner in the array of adorners returned by xref:System.Windows.Documents.AdornerLayer.GetAdorners%2A. This example happens to retrieve the adorners on a xref:System.Windows.UIElement named myTextBox. If the element specified in the call to xref:System.Windows.Documents.AdornerLayer.GetAdorners%2A has no adorners, null is returned. This code explicitly checks for a null array, and is best suited for applications where a null array is expected to be relatively common.

Example
This condensed code example is functionally equivalent to the verbose example shown above. This code does not explicitly check for a null array, so it is possible that a xref:System.NullReferenceException exception may be raised. This code is best suited for applications where a null array is expected to be rare.
