PhoneApplicationPage 之观察

PhoneApplicationPage 的属性 Landscape" Orientation="Portrait"在landscape  和portrait 之间变化的时候 会触发内部控件的大小的改变 触发SizeChanged事件

  private void ContentPanel_SizeChanged(object sender, SizeChangedEventArgs e)
        {
            txtblk.Text = String.Format("ContentPanel size: {0}\n" +
                                        "TitlePanel size: {1}\n" +
                                        "LayoutRoot size: {2}\n" +
                                        "MainPage size: {3}\n" +
                                        "Frame size: {4}",
                                        e.NewSize,
                                        new Size(TitlePanel.ActualWidth, TitlePanel.ActualHeight),
                                        new Size(LayoutRoot.ActualWidth, LayoutRoot.ActualHeight),
                                        new Size(this.ActualWidth, this.ActualHeight),
                                        Application.Current.RootVisual.RenderSize);

        }
