The following example demonstrates how to determine the position of the stylus when the user lifts it from the tablet. This example assumes that there is a TextBox called textBox1 and that the PreviewStylusUp event is connected to the event handlers.
void textbox1_PreviewStylusUp(object sender, StylusEventArgs e)
{
Point pos = e.GetPosition(textbox1);
textbox1.AppendText("X: " + pos.X + " Y: " + pos.Y + "\n");
}
Private Sub textbox1_PreviewStylusUp(ByVal sender As Object, _
ByVal e As StylusEventArgs) Handles textbox1.PreviewStylusUp
Dim pos As Point = e.GetPosition(textbox1)
textbox1.AppendText("X: " & pos.X & " Y: " & pos.Y & 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.
