StylusEventHandler

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 change the color of a Button when the stylus cursor enters and leaves its bounds. This example assumes that there is a Button called button1 and that the StylusEnter and StylusLeave events are connected to the event handlers.

Private originalColor As Brush

Private Sub button1_StylusLeave(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles button1.StylusLeave

    button1.Background = originalColor

End Sub 'button1_StylusLeave

Private Sub button1_StylusEnter(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles button1.StylusEnter

    originalColor = button1.Background
    button1.Background = Brushes.Gray

End Sub 'button1_StylusEnter
