Routing strategy




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 the position of the stylus when the user lifts it from the tablet. This example assumes that there is a TextBox called textBox1 and that the PreviewStylusUp event is connected to the event handlers.

void textbox1_PreviewStylusUp(object sender, StylusEventArgs e)
    Point pos = e.GetPosition(textbox1);
    textbox1.AppendText("X: " + pos.X + " Y: " + pos.Y + "\n");
