The following example demonstrates how to copy the selected text when the user releases the barrel button on a stylus. This example assumes that there is a TextBox called textBox1, and that the StylusButtonUp event is connected to the event handlers.
void textbox1_StylusButtonUp(object sender, StylusButtonEventArgs e)
{
if (e.StylusButton.Guid != StylusPointProperties.BarrelButton.Id)
{
return;
}
if (textbox1.SelectedText == "")
{
return;
}
Clipboard.SetDataObject(textbox1.SelectedText);
}
Private Sub textbox1_StylusButtonUp(ByVal sender As Object, ByVal e As StylusButtonEventArgs) _
Handles textbox1.StylusButtonUp
If e.StylusButton.Guid <> StylusPointProperties.BarrelButton.Id Then
Return
End If
If textbox1.SelectedText = "" Then
Return
End If
Clipboard.SetDataObject(textbox1.SelectedText)
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.
