Occurs when the user presses one of the buttons on the stylus.

Assembly:  PresentationCore (in PresentationCore.dll)

See AddStylusButtonDownHandler, RemoveStylusButtonDownHandler

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.
Private Sub textbox1_StylusButtonDown(ByVal sender As Object, ByVal e As StylusButtonEventArgs) _
    Handles textbox1.StylusButtonDown

    If e.StylusButton.Guid <> StylusPointProperties.BarrelButton.Id Then
    End If

    If textbox1.ContextMenu Is Nothing Then
        textbox1.ContextMenu = textBoxContextMenu
        textbox1.ContextMenu = Nothing
    End If

End Sub 'textbox1_StylusButtonDown
