Handling Orientation in Silverlight for Symbian

One obvious thing in modern symbian mobiles, is how to detect orientation.
I am currently porting some Silverlight 1.0 samples like GrandPiano to Silverlight for Symbian and I was wondering
how can I detect the phone orientation. Well I just analysed the Bing demo and find out that is kind of simple.

What you need is something like this:

public static readonly DependencyProperty OrientationProperty = 
   DependencyProperty.Register("Orientation", typeof(Orientation), typeof(Page), 
    new PropertyMetadata((Orientation)0, new PropertyChangedCallback(OrientationPropertyChanged)));

private static void OrientationPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
     (sender as GrandPiano).UpdateOrientation();
}

private void UpdateOrientation()
{
   base.Width = (this.Orientation == Orientation.Vertical) ? DeviceVerticalSize.Width : DeviceVerticalSize.Height;
   base.Height = (this.Orientation == Orientation.Vertical) ? DeviceVerticalSize.Height : DeviceVerticalSize.Width;
   base.Clip = new RectangleGeometry { Rect = new Rect(new Point(), new Size(base.Width, base.Height)) };
}

// Properties
public Orientation Orientation
{
   get
    {
       return (Orientation)base.GetValue(OrientationProperty);
    }
   set
    {
       base.SetValue(OrientationProperty, value);
    }
}
