我将 WPF WebBrowser 控件拖到我的 Blend 项目中，然后将源分配为 HTML5 页面。我想在我的 WPF 应用程序中使用 LobsterPot HTML5 PivotViewer(url: LobsterPot HTML5 PivotViewer)。

页面加载，然后我在浏览器顶部收到一条通知，说活动内容已被阻止，当我单击允许时，屏幕保持空白。屏幕上不显示任何内容。任何人都可以指导我并解释我哪里出错了......

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            this.InitializeComponent();

            // Insert code required on object creation below this point.
        }

        private void BackButton_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
        {
            // TODO: Add event handler implementation here.
            MyWebBrowser.GoBack();
        }

        private void GoButton_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
        {
            // TODO: Add event handler implementation here.
            MyWebBrowser.Navigating += new NavigatingCancelEventHandler(MyWebBrowser_Navigating);
            MyWebBrowser.Navigated += new NavigatedEventHandler(MyWebBrowser_Navigated);
            string address = UriFieldTextBox.Text.ToString().Trim();
            MyWebBrowser.Navigate(new Uri(address,UriKind.RelativeOrAbsolute));
        }

        private void NextButton_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
        {
            // TODO: Add event handler implementation here.
            MyWebBrowser.GoForward();
        }

        private void MyWebBrowser_Loaded(object sender, System.Windows.RoutedEventArgs e)
        {
            // TODO: Add event handler implementation here.
            MyWebBrowser.Navigating += new NavigatingCancelEventHandler(MyWebBrowser_Navigating);
            MyWebBrowser.Navigated+=new NavigatedEventHandler(MyWebBrowser_Navigated);
            Uri uri = new Uri("C:\\Users\\Manthravadi\\Desktop\\lobsterpothtml5pivotviewer-0.6.8\\examples\\PASS Summit 2011.html",UriKind.Absolute);
            MyWebBrowser.Source= uri;
        }



        void MyWebBrowser_Navigating(object sender,NavigatingCancelEventArgs args){
            MessageBox.Show("Page is Loading ...\n\nPlease wait");
        }

        void MyWebBrowser_Navigated(object sender, NavigationEventArgs args){
            MessageBox.Show("Page has been Loaded ...!");
        }

此外，当我在 UriFieldTextBox 中键入诸如“http://google.com”（不带引号）之类的地址并按“执行”按钮时，没有加载页面，有人可以解释我哪里出错了吗？
