Ejemplos

El ejemplo siguiente se controla el TouchUp eventos que se producen en un Canvas.The following example handles the TouchUp events that occur on a Canvas. Comprueba la Captured propiedad para comprobar que el dispositivo que generó el evento se captura en el Canvas.It checks the Captured property to verify that the device that raised the event is captured to the Canvas. Si es así, el TouchDevice se libera.If it is, the TouchDevice is released.

Este ejemplo forma parte de un ejemplo más extenso que está disponible en el TouchDevice información general de clases.This example is part of a larger example that is available in the TouchDevice class overview.

private void canvas_TouchUp(object sender, TouchEventArgs e)
{
    Canvas _canvas = (Canvas)sender as Canvas;
    if (_canvas != null && e.TouchDevice.Captured == _canvas)
    {
        _canvas.ReleaseTouchCapture(e.TouchDevice);
    }
}
' Touch Up
Private Sub canvas_TouchUp(ByVal sender As System.Object, ByVal e As System.Windows.Input.TouchEventArgs)
    Dim _canvas As Canvas = CType(sender, Canvas)
    If (_canvas IsNot Nothing AndAlso e.TouchDevice.Captured Is _canvas) Then
        _canvas.ReleaseTouchCapture(e.TouchDevice)

    End If
End Sub
