    <p>I wonder how I can show design time data in Expression Blend that is located inside a SampleData.xaml using a CollectionViewSource? Before changing my code to use the CVS, I used an ObservableCollection. I was in the need to filter and sort the items inside there, thus I changed the code to use the CVS. Now my designer complains about not being able to fill the SampleData's NextItems with a proper structure to show up in Expression Blend. Here is some code I use inside the app:</p> <p>MainViewModel.cs</p> <pre><code>class MainViewModel { public MainViewModel() { AllItems = new ObservableCollection&lt;ItemViewModel&gt;(); NextItems = new CollectionViewSource(); NextItems.Source = AllItems; } public CollectionViewSource NextItems { get; private set; } public ObservableCollection&lt;ItemViewModel&gt; AllItems { get; private set; } some functions to fill, filter, sort etc... } </code></pre> <p>MainView.xaml:</p> <pre><code>&lt;phone:PhoneApplicationPage ... some other stuff ... d:DesignWidth="480" d:DesignHeight="728" d:DataContext="{d:DesignData SampleData/SampleData.xaml}"&gt; &lt;Grid x:Name="LayoutRoot" Background="Transparent"&gt; &lt;controls:Panorama&gt; &lt;controls:PanoramaItem&gt; &lt;ListBox ItemsSource="{Binding NextItems.View}"&gt; &lt;ListBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;StackPanel&gt; &lt;Image Source="{Binding Image}" /&gt; &lt;StackPanel&gt; &lt;TextBlock Text="{Binding FullName}" /&gt; &lt;/StackPanel&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;/ListBox.ItemTemplate&gt; &lt;/ListBox&gt; &lt;/controls:PanoramaItem&gt; &lt;/controls:Panorama&gt; &lt;/Grid&gt; &lt;/phone:PhoneApplicationPage&gt; </code></pre> <p>SampleData.xaml</p> <pre><code>&lt;local:MainViewModel xmlns:local="clr-namespace:MyAppNamespace" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:swd="clr-namespace:System.Windows.Data;assembly=System.Windows" &gt; &lt;local:MainViewModel.AllItems&gt; &lt;local:ItemModel FullName="Dummy" Image="/Images/dummy.png" /&gt; &lt;/local:MainViewModel.AllItems&gt; &lt;local:MainViewModel.NextItems&gt; How to fill the CollectionViewSource's Source? &lt;/local:MainViewModel.NextItems&gt; &lt;/local:MainViewModel&gt; </code></pre> <p>So the question I can't find an answer to is how to fill the Source for NextItems in SampleDate.xaml? Any help would be much appreciated.</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.
