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 determine which element the stylus is positioned over. This example assumes that there is a TextBox called textBox1, and that the PreviewStylusInAirMove event is connected to the event handler.

Private Sub Window1_PreviewStylusInAirMove(ByVal sender As Object, _
    ByVal e As StylusEventArgs) Handles Me.PreviewStylusInAirMove

    Dim element As Object
    element = CType(Stylus.DirectlyOver, Object)
    textbox1.AppendText(element.ToString() & vbLf)

End Sub 'Window1_PreviewStylusInAirMove
