How to: Remove all Adorners from an Element

This example shows how to programmatically remove all adorners from a specified UIElement.

This verbose code example removes all of the adorners in the array of adorners returned by GetAdorners. This example happens to retrieve the adorners on a UIElement named myTextBox. If the element specified in the call to GetAdorners 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.

            toRemoveArray = myAdornerLayer.GetAdorners(myTextBox)
		If toRemoveArray IsNot Nothing Then
		  For x As Integer = 0 To toRemoveArray.Length - 1
			myAdornerLayer.Remove(toRemoveArray(x))
		  Next x
		End If

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 NullReferenceException exception may be raised. This code is best suited for applications where a null array is expected to be rare.

		Try
                For Each toRemove In myAdornerLayer.GetAdorners(myTextBox)
                    myAdornerLayer.Remove(toRemove)
                Next toRemove
		Catch
		End Try
