Comentarios

Se envía un evento Tapped cada vez que se hace clic en un mouse o se pulsa un dedo o lápiz en el objeto.

Constructores

TappedRoutedEventArgs()

Inicializa una nueva instancia de la clase TappedRoutedEventArgs .

Propiedades

Handled	Obtiene o establece un valor que marca el evento enrutado como controlado. Un valor true para Handled impide que la mayoría de los controladores a lo largo de la ruta de eventos controlen de nuevo el mismo evento.
OriginalSource	Obtiene una referencia al objeto que generó el evento. Suele ser una parte de plantilla de un control en lugar de un elemento que se declaró en la interfaz de usuario de la aplicación. (Heredado de RoutedEventArgs)
PointerDeviceType	Obtiene pointerDeviceType para el dispositivo de puntero que inició el evento de entrada asociado.

Métodos

GetPosition(UIElement)

Devuelve las coordenadas x e y de la posición del puntero, que opcionalmente se evalúan con respecto a un origen de coordenadas de un UIElement proporcionado.
