在我的 Windows 手机应用程序中,我使用 RichTextBox 元素
我上面有一个超链接,当用户点击它时会出现一个对话框:你想在外部浏览器中打开这个链接吗?如果用户拒绝,则不应打开外部浏览器。我取消导航,但无论如何 - 外部浏览器打开。如何取消浏览器中的打开链接?

var phoneApplicationFrame = Application.Current.RootVisual as PhoneApplicationFrame;
if (Application.Current.RootVisual as PhoneApplicationFrame != null)
{
phoneApplicationFrame.Navigating += new NavigatingCancelEventHandler(NavigationService_Navigating);
}
}
link.Foreground = new SolidColorBrush(Colors.Blue);
link.MouseOverForeground = new SolidColorBrush(Colors.Blue);
link.TargetName = "_blank";
var linkText = new Run() { Text = linkDesc };
link.Inlines.Add(linkText);
link.Click += new RoutedEventHandler(NavidateTo);
private static void NavidateTo(object sender, RoutedEventArgs routedEventArgs)
{
if (MessageBox.Show(
Constants.BrowserNavigating,
"",
MessageBoxButton.OKCancel) == MessageBoxResult.Cancel)
{
StateManager.Set("ExternalBrowser", "true");
}
else
{
StateManager.Set("Browser", "true");
}
}
public static void NavigationService_Navigating(object sender, NavigatingCancelEventArgs e)
{
var res = StateManager.Get("ExternalBrowser");
if (res != null)
{
StateManager.Remove("ExternalBrowser");
e.Cancel = true;
}
}
