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 show a shortcut menu when the user presses the barrel button on a stylus. This example assumes that there is a TextBox called textBox1, and a ContextMenu called textBoxContextMenu, and that the StylusButtonDown event is connected to the event handler.

// Show or hide a shortcut menu when the user clicks the barrel button.
void textbox1_StylusButtonDown(object sender, StylusButtonEventArgs e)
    if (e.StylusButton.Guid != StylusPointProperties.BarrelButton.Id)

    if (textbox1.ContextMenu == null)
        textbox1.ContextMenu = textBoxContextMenu;
        textbox1.ContextMenu = null;
