    copied!<p>I have a databound xml reader. MainPage is connected to DetailsPage: When user clicks on the name in Main Page, She gets the details of this name (Age, Gender, Date of Birth etc.) in the DetailsPage.</p> <p>I am in trouble with tombstoning atm. When I click on windows button, then click on back button I get into an empty DetailsPage.</p> <p>What would be the easiest way to solve this problem? I tried to use TombstoneHelper but it also shows empty page.</p> <p>DetailsPage.xaml </p> <pre><code> &lt;controls:PanoramaItem Header="" Margin="0,0,0,80"&gt; &lt;ScrollViewer&gt; &lt;StackPanel&gt; &lt;TextBlock TextWrapping="Wrap" Width="432" Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="0,0,0,10" d:LayoutOverrides="Width" Foreground="#DEFFFFFF"&gt;&lt;Run Text="Personal D"/&gt;&lt;Run Text="e"/&gt;&lt;Run Text="tails"/&gt;&lt;/TextBlock&gt; &lt;StackPanel HorizontalAlignment="Left" Width="432" Orientation="Horizontal"&gt; &lt;TextBlock TextWrapping="Wrap" Margin="20,0,7,0" Foreground="#DEFFFFFF"&gt;&lt;Run Text="Name"/&gt;&lt;Run Text=":"/&gt;&lt;/TextBlock&gt; &lt;TextBlock x:Name="username" TextWrapping="Wrap" Text="{Binding Name}" Foreground="#DEFFFFFF" /&gt; &lt;/StackPanel&gt; &lt;StackPanel HorizontalAlignment="Left" Width="432" Orientation="Horizontal"&gt; &lt;TextBlock TextWrapping="Wrap" Margin="20,0,7,0" Foreground="#DEFFFFFF"&gt;&lt;Run Text="Age"/&gt;&lt;Run Text=":"/&gt;&lt;/TextBlock&gt; &lt;TextBlock x:Name="age" TextWrapping="Wrap" Text="{Binding Age}" Foreground="#DEFFFFFF"/&gt; &lt;/StackPanel&gt; &lt;StackPanel HorizontalAlignment="Left" Width="432" Orientation="Horizontal"&gt; &lt;TextBlock TextWrapping="Wrap" Margin="20,0,7,0" Foreground="#DEFFFFFF"&gt;&lt;Run Text="Nationality"/&gt;&lt;Run Text=":"/&gt;&lt;/TextBlock&gt; &lt;TextBlock x:Name="country" TextWrapping="Wrap" Text="{Binding Country}" Foreground="#DEFFFFFF"/&gt; &lt;/StackPanel&gt; &lt;StackPanel HorizontalAlignment="Left" Width="432" Orientation="Horizontal"&gt; &lt;TextBlock TextWrapping="Wrap" Margin="20,0,7,0" Foreground="#DEFFFFFF"&gt;&lt;Run Text="Country of Birth"/&gt;&lt;Run Text=":"/&gt;&lt;/TextBlock&gt; &lt;TextBlock x:Name="cobirth" TextWrapping="Wrap" Text="{Binding Cobirth}" Foreground="#DEFFFFFF"/&gt; &lt;/StackPanel&gt; &lt;StackPanel HorizontalAlignment="Left" Width="432" Orientation="Horizontal"&gt; &lt;TextBlock TextWrapping="Wrap" Margin="20,0,7,0" Foreground="#DEFFFFFF"&gt;&lt;Run Text="Place of Birth"/&gt;&lt;Run Text=":"/&gt;&lt;/TextBlock&gt; &lt;TextBlock x:Name="fobirth" TextWrapping="Wrap" Text="{Binding Pobirth}" Foreground="#DEFFFFFF"/&gt; &lt;/StackPanel&gt; &lt;/StackPanel&gt; &lt;/ScrollViewer&gt; &lt;/controls:PanoramaItem&gt; </code></pre> <p>DetailsPage.cs </p> <p>using TombstoneHelper;</p> <pre><code> public User() { InitializeComponent(); SupportedOrientations = SupportedPageOrientation.Portrait; } protected override void OnNavigatedFrom(System.Windows.Navigation.NavigationEventArgs e) { base.OnNavigatedFrom(e); this.SaveState(); // &lt;- first line } protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e) { base.OnNavigatedTo(e); this.RestoreState(); // &lt;- second line } </code></pre> <p>Mainpage.Cs</p> <pre><code> private void UserListBox_SelectionChanged(object sender, SelectionChangedEventArgs e) { if (e.AddedItems.Count &gt; 0) { NavigationService.Navigate(new Uri("/DetailsPage.xaml", UriKind.Relative)); FrameworkElement root = Application.Current.RootVisual as FrameworkElement; root.DataContext = (RosterItem)e.AddedItems[0]; ((ListBox)sender).SelectedIndex = -1; } } </code></pre>

An individual column

Larger individual text columns get their own page to allow for proper reading.
