Body
I have a list of theaters and I created a secondary tile from my application to navigate directly to specific theater. I pass the id of the theater in query string : I load the theaters from a WCF service in the file "MainViewModel.cs" In my home page, I have a list of theaters and I can navigate to a details page. But when I want to navigate from the tile, I have an error... The Tile : <pre><code>ShellTile.Create(new Uri("/TheaterDetails.xaml?selectedItem=" + theater.idTheater, UriKind.Relative), tile, false); </code></pre> My TheaterDetails page : <pre><code> public partial class TheaterDetails : PhoneApplicationPage { theater theater = new theater(); public TheaterDetails() { InitializeComponent(); } protected override void OnNavigatedTo(NavigationEventArgs e) { if (!App.ViewModel.IsDataLoaded) { App.ViewModel.LoadData(); } if (DataContext == null) { string selectedIndex = ""; if (NavigationContext.QueryString.TryGetValue("selectedItem", out selectedIndex)) { int index = int.Parse(selectedIndex); theater = (from t in App.ViewModel.Theaters where t.idTheater == index select t).SingleOrDefault(); DataContext = theater; .... .... .... </code></pre> The error : <a href="https://dl.dropboxusercontent.com/u/9197067/error.png" rel="nofollow">https://dl.dropboxusercontent.com/u/9197067/error.png</a> Like if the data were not loaded... Do you have an idea where the problem come from ? The solution could be easy but I am a beginner... Maybe it's because I load the data asynchronously and the application doesn't wait until it's done... Thanks EDIT : My LoadData() method : <pre><code> public void LoadData() { client.GetTheatersCompleted += new EventHandler<ServiceReference1.GetTheatersCompletedEventArgs>(client_GetTheatersCompleted); client.GetTheatersAsync(); // Other get methods... this.IsDataLoaded = true; } private void client_GetTheatersCompleted(object sender, ServiceReference1.GetTheatersCompletedEventArgs e) { Theaters = e.Result; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
