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 whether the stylus is inverted. This example assumes that there is a TextBox called textBox1 and that the PreviewStylusInRange event is connected to the event handlers.

void textbox1_PreviewStylusInRange(object sender, StylusEventArgs e)
{
    if (e.StylusDevice.Inverted)
    {
        textbox1.AppendText("Pen is inverted\n");
    }
    else
    {
        textbox1.AppendText("Pen is not inverted\n");
    }
}
Private Sub textbox1_PreviewStylusInRange(ByVal sender As Object, _
    ByVal e As StylusEventArgs) Handles textbox1.PreviewStylusInRange

    If e.StylusDevice.Inverted Then
        textbox1.AppendText("Pen is inverted" & vbLf)
    Else
        textbox1.AppendText("Pen is not inverted" & vbLf)
    End If

End Sub 'textbox1_PreviewStylusInRange
