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
