The following example demonstrates how to determine which button raised the PreviewStylusButtonDown event. This example assumes that there is a TextBox called textBox1 and that the PreviewStylusButtonDown event is connected to the event handlers.
void textbox1_PreviewStylusButtonDown(object sender, StylusButtonEventArgs e)
{
textbox1.AppendText(e.StylusButton.Name + "\n");
}
Private Sub textbox1_PreviewStylusButtonDown(ByVal sender As Object, _
ByVal e As StylusButtonEventArgs) Handles textbox1.PreviewStylusButtonDown
textbox1.AppendText(e.StylusButton.Name & vbLf)
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.
