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 example demonstrates how to determine the position of the stylus when it moves. This example assumes that there is a TextBox called textBox1 and that the PreviewStylusMove event is connected to the event handlers.

void textbox1_PreviewStylusMove(object sender, StylusEventArgs e)
    Point pos = e.GetPosition(textbox1);
    textbox1.AppendText("X: " + pos.X + " Y: " + pos.Y + "\n");
