 static CustomControl()
 {
     DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl), new FrameworkPropertyMetadata(typeof(CustomControl)));
     CustomControl.ClearCommand = new RoutedUICommand();
     CommandBinding ClearCommandBinding=new CommandBinding(CustomControl.ClearCommand,CustomControl.ClearText);
