XAMLPARSEException по инициализации компонента WP8

Question

Как титул говорит, что я получаю XAMLPARSEException, когда я пытаюсь запустить приложение.Я только начал изучать XAML и в данный момент после учета книги под названием «Windows Phone 8 Game Development» здесь является исключением, что это дает мне.

system.windows.markap.xamlparseException Hresult= -2146233087. Сообщение= Свойство «System.windows.controls.panel.children» устанавливается более одного раза.[Строка: 53 позиции: 74] Source= System.Windows. Linenumber= 53. Синсопозиция= 74. Трассировки стека: На System.Windows.Application.LoadComponent (Компонент объектов, URI Resourcelocator) В Spaceaim3d.views.menupage.initializecomponent () В Spaceaim3d.views.menupage..ctor () Innerexception:

Вот мой код

 public partial class MenuPage : PhoneApplicationPage
{
    private Dictionary<String, String> m_urls = new Dictionary<string, string>();

    public MenuPage()
    {
        InitializeComponent();
        m_urls["play"] = "/Views/GamePage.xaml";
        m_urls["ranks"] = "/Views/RanksPage.xaml";
        m_urls["map"] = "/Views/MapPage.xaml";
        m_urls["world"] = "/Views/WorldPage.xaml";
        m_urls["help"] = "/Views/HelpPage.xaml";
        m_urls["web"] = "/Views/WebPage.xaml";
        m_urls["settings"] = "/Views/SettingsPage.xaml";
    }

    //This is a common event handler used by all entities on menu page
    private void BrdPage_Tap(object sender, GestureEventArgs e)
    {
        //To get the tag name we case the sender object and get the tag as a string
        String page = ((Border)sender).Tag as String;
        NavigationService.Navigate(new Uri(m_urls[page], UriKind.Relative));
    }
}

.

А вот мой код xaml

Answer 1

Я переместил весь код XAML с границами над Gridgebackground, и он работал
