This is an attached event. WPF implements attached events as routed events. An attached event is, fundamentally, a XAML language concept used to reference events that are handled on objects that do not, themselves, define events. WPF further expands an attached event's capabilities, allowing it to traverse a route. Attached events do not have a direct handling syntax in code; to attach handlers for a routed event in code, use a designated Add*Handler method. For details, see Attached Events Overview.
The following example demonstrates how to ensure that the stylus is not captured when the user touches the stylus to the tablet. This example assumes that the event is connected to the event handler.
Private Sub Window1_PreviewStylusDown(ByVal sender As Object, ByVal e As StylusDownEventArgs) _ Handles Me.PreviewStylusDown Dim capturedElement As IInputElement = Stylus.Captured If Not (capturedElement Is Nothing) Then capturedElement.ReleaseStylusCapture() End If End Sub 'Window1_PreviewStylusDown
