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 event handlers.
Brush originalColor;
void button1_StylusLeave(object sender, StylusEventArgs e)
{
button1.Background = originalColor;
}
void button1_StylusEnter(object sender, StylusEventArgs e)
{
originalColor = button1.Background;
button1.Background = Brushes.Gray;
}
Private originalColor As Brush
Private Sub button1_StylusLeave(ByVal sender As Object, ByVal e As StylusEventArgs) _
Handles button1.StylusLeave
button1.Background = originalColor
End Sub
Private Sub button1_StylusEnter(ByVal sender As Object, ByVal e As StylusEventArgs) _
Handles button1.StylusEnter
originalColor = button1.Background
button1.Background = Brushes.Gray
End Sub
Remarks
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.
