Examples

The following example demonstrates how to change the background color of a TextBox when the TextBox captures and releases stylus events. This example assumes that there is a textbox called textBox1, and that the GotStylusCapture and LostStylusCapture events are connected to the event handlers in the example.

void textbox1_LostStylusCapture(object sender, StylusEventArgs e)
{
    textbox1.Background = Brushes.White;
}

void textbox1_GotStylusCapture(object sender, StylusEventArgs e)
{
    textbox1.Background = Brushes.Red;
}
Private Sub textbox1_LostStylusCapture(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles textbox1.LostStylusCapture

    textbox1.Background = Brushes.White

End Sub


Private Sub textbox1_GotStylusCapture(ByVal sender As Object, ByVal e As StylusEventArgs) _
    Handles textbox1.GotStylusCapture

    textbox1.Background = Brushes.Red

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.
