パノラマアイテムをパノラマコントロールに動的に追加していますが、問題なく正常に追加されています

しかし、リストボックスをパノラマアイテムに追加しようとすると、エラーが発生します。例外も表示されません。アプリケーションが自動的に閉じ、その後エミュレータのホーム画面が表示されます。

以下は、パノラマアイテムとリストボックスを作成するために作成したコードです。

lstAnniversaries = new ListBox()
lstAnniversaries.Width = 420;
                        lstAnniversaries.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
                        lstAnniversaries.Foreground = new SolidColorBrush(FacebookQueries.GetColorFromHexString("#000000"));
                        lstAnniversaries.Background = new SolidColorBrush(FacebookQueries.GetColorFromHexString("#ffffff"));
                        lstAnniversaries.Tap += new EventHandler<System.Windows.Input.GestureEventArgs>(lstUpcoming_Tap);
                        lstAnniversaries.ItemTemplate = (DataTemplate)XamlReader.Load(@"<DataTemplate xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"" xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml"">

            </Button>
        </Grid>
    </DataTemplate>");
                        pan_anniversaries = new PanoramaItem();
                        pan_anniversaries.HeaderTemplate =     (DataTemplate)XamlReader.Load(@"<DataTemplate     xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation""     xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml""><TextBlock Text=""anniversaries""    FontSize=""54"" Foreground=""Black"" Margin=""-10,0,0,0""></TextBlock></DataTemplate>");

                        Grid grd = new Grid();
                        grd.Children.Add(lstAnniversaries);

                        pan_anniversaries.Content = grd;

                        PanoramaControl.Items.Add(pan_anniversaries);

DataTemplatesコードファイルで作成する代わりにDataTemplate、ページまたはAPPのリソースセクションにコードを追加します。

コメントで@igraliが言及したように、次の方法を使用すると問題が解決します

 lstAnniversaries.ItemTemplate = this.Resources["AnniversariesTemplate"] as DataTemplate;
 lstAnniversaries.Style = this.Resources["EventsListStyle"] as Style;
