    <p>I have problem that i just cant figure out right now. I am trying to develop a Windows-8 style app and im stuck implementing this functionality.</p> <p>I have a <strong>MainWindow</strong> which contains a ListBox and a Button (lets say <strong>addButton</strong>).</p> <p>When i click the button i navigate to a new page, lets say <strong>AddCustomerPage</strong> with this.Frame.Navigate(typeof (AddCustomerPage));</p> <p><strong>AddCustomerPage</strong> has 1 textBox and 1 button (lets say <strong>doneButton</strong>. When i click the button i want the string in the textBox to be added to the ListBox on the previous page.</p> <p>This is my current functionality: 1. MainWindow is created.</p> <ol> <li><p>Click addButton</p></li> <li><p>AddCustomer page is created. MainWindow is destroyed(problem).</p></li> <li><p>Click doneButton</p></li> <li><p>A MainWindow object is created with a ListBox with 1 item.</p></li> <li><p>Repeat the add process, i always get a MainWindow with a ListBox with 1 item.</p></li> </ol> <p>Thanks for the help. Here is the code:</p> <pre><code>public sealed partial class MainPage : Page { public MainPage() { this.InitializeComponent(); this.brainPageController = new PageController(); // add items from the List&lt;String&gt; to the listBox listGoals.ItemsSource = brainPageController.GetListGoals(); } protected override void OnNavigatedTo(NavigationEventArgs e) { var parameter = e.Parameter as String; // a simple controller that adds a string to a List&lt;string&gt; brainPageController.AddGoal(parameter); } private void addButton_Click(object sender, RoutedEventArgs e) { this.Frame.Navigate(typeof (GoalsInfo)); } // VARIABLES DECLARATION private PageController brainPageController; } public sealed partial class GoalsInfo : WinGoalsWIP.Common.LayoutAwarePage { public GoalsInfo() { this.InitializeComponent(); this.brainPageController = new PageController(); } protected override void LoadState(Object navigationParameter, Dictionary&lt;String, Object&gt; pageState) { } protected override void SaveState(Dictionary&lt;String, Object&gt; pageState) { } private void Button_Click_1(object sender, RoutedEventArgs e) { brainPageController.AddGoal(nameTextBox.Text); this.Frame.Navigate(typeof(MainPage), nameTextBox.Text); } // VARIABLES DECLARATION PageController brainPageController; } </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.
