    <p>After many attempts to run this functionality finally I got absolutely lost. Only the group headers are shown and only in ZoomInView. Where I'm wrong? All my data is loaded from web api services, but I think that the CollectionViewSource is observable and this will not be the source of the problem.</p> <p>These are my poco classes</p> <pre><code>public class StopInformation { public string Name { get; set; } public string Number { get; set; } } public class ScheduleDirection { public string Direction { get; set; } public IEnumerable&lt;StopInformation&gt; Stops { get; set; } } </code></pre> <p>ViewModel Member</p> <pre><code>public ObservableCollection&lt;ScheduleDirection&gt; Directions { get; set; } </code></pre> <p>In my page xaml resources</p> <pre><code>&lt;CollectionViewSource x:Name="cvs" IsSourceGrouped="true" Source="{Binding Directions}" /&gt; </code></pre> <p>And the semantic zoom code:</p> <pre><code>&lt;SemanticZoom x:Name="semanticZoom"&gt; &lt;SemanticZoom.ZoomedOutView&gt; &lt;GridView ItemsSource="{Binding Path=View.CollectionGroups, Source={StaticResource cvs}}" ScrollViewer.IsHorizontalScrollChainingEnabled="False"&gt; &lt;GridView.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{Binding Direction}"/&gt; &lt;/DataTemplate&gt; &lt;/GridView.ItemTemplate&gt; &lt;GridView.ItemsPanel&gt; &lt;ItemsPanelTemplate&gt; &lt;WrapGrid /&gt; &lt;/ItemsPanelTemplate&gt; &lt;/GridView.ItemsPanel&gt; &lt;/GridView&gt; &lt;/SemanticZoom.ZoomedOutView&gt; &lt;SemanticZoom.ZoomedInView&gt; &lt;GridView ItemsSource="{Binding Source={StaticResource cvs}}" IsSwipeEnabled="True" ScrollViewer.IsHorizontalScrollChainingEnabled="False"&gt; &lt;GridView.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text="{Binding Name}" /&gt; &lt;/DataTemplate&gt; &lt;/GridView.ItemTemplate&gt; &lt;GridView.GroupStyle&gt; &lt;GroupStyle&gt; &lt;GroupStyle.HeaderTemplate&gt; &lt;DataTemplate&gt; &lt;TextBlock Text='{Binding Direction}' /&gt; &lt;/DataTemplate&gt; &lt;/GroupStyle.HeaderTemplate&gt; &lt;GroupStyle.ContainerStyle&gt; &lt;Style TargetType="GroupItem"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="GroupItem"&gt; &lt;StackPanel Orientation="Vertical"&gt; &lt;ContentPresenter Content="{TemplateBinding Content}" /&gt; &lt;ItemsControl x:Name="ItemsControl" ItemsSource="{Binding Stops}" /&gt; &lt;/StackPanel&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; &lt;/GroupStyle.ContainerStyle&gt; &lt;/GroupStyle&gt; &lt;/GridView.GroupStyle&gt; &lt;Button Visibility="Collapsed"/&gt; &lt;/GridView&gt; &lt;/SemanticZoom.ZoomedInView&gt; &lt;/SemanticZoom&gt; </code></pre> <p>Accept any ideas.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
