    <p>I'm thinking something like this should work right out of the box:</p> <pre><code>&lt;UserControl.Resources&gt; &lt;DataTemplate DataType="{x:Type vm:GenericQuestionViewModel}"&gt; &lt;v:GenericQuestion/&gt; &lt;/DataTemplate&gt; &lt;DataTemplate DataType="{x:Type tvm:GeographyQuestionViewModel}"&gt; &lt;tv:GeographyQuestion/&gt; &lt;/DataTemplate&gt; &lt;DataTemplate DataType="{x:Type tvm:BiologyQuestionViewModel}"&gt; &lt;tv:BiologyQuestion/&gt; &lt;/DataTemplate&gt; &lt;/UserControl.Resources&gt; &lt;ContentControl Content="{Binding QuestionViewModel}"&gt; </code></pre> <hr> <p><strong>Edit:</strong></p> <p>Yes, this definitely should work. Here's a more complete example:</p> <p><strong>Main View Model</strong></p> <pre><code>public class MainWindowViewModel : ViewModelBase { public ObservableCollection&lt;QuestionViewModel&gt; QuestionViewModels { get; set; } public MainWindowViewModel() { QuestionViewModels = new ObservableCollection&lt;QuestionViewModel&gt; { new GenericQuestionViewModel(), new GeographyQuestionViewModel(), new BiologyQuestionViewModel() }; } } </code></pre> <p><strong>Question View Models</strong></p> <pre><code>public abstract class QuestionViewModel : ViewModelBase { } public class GenericQuestionViewModel : QuestionViewModel { } public class GeographyQuestionViewModel : QuestionViewModel { } public class BiologyQuestionViewModel : QuestionViewModel { } </code></pre> <p><strong>Question User Controls</strong></p> <pre><code>&lt;UserControl x:Class="WpfApplication1.GenericQuestion" ...&gt; &lt;Grid&gt; &lt;TextBlock Text="Generic Question" /&gt; &lt;/Grid&gt; &lt;/UserControl&gt; &lt;UserControl x:Class="WpfApplication1.GeographyQuestion" ...&gt; &lt;Grid&gt; &lt;TextBlock Text="Geography Question" /&gt; &lt;/Grid&gt; &lt;/UserControl&gt; &lt;UserControl x:Class="WpfApplication1.BiologyQuestion" ...&gt; &lt;Grid&gt; &lt;TextBlock Text="Biology Question" /&gt; &lt;/Grid&gt; &lt;/UserControl&gt; </code></pre> <p><strong>Main Window</strong></p> <pre><code>&lt;Window x:Class="WpfApplication1.MainWindow" ... Title="MainWindow" Height="900" Width="525"&gt; &lt;Window.DataContext&gt; &lt;local:MainWindowViewModel /&gt; &lt;/Window.DataContext&gt; &lt;Window.Resources&gt; &lt;DataTemplate DataType="{x:Type local:GenericQuestionViewModel}"&gt; &lt;local:GenericQuestion /&gt; &lt;/DataTemplate&gt; &lt;DataTemplate DataType="{x:Type local:GeographyQuestionViewModel}"&gt; &lt;local:GeographyQuestion /&gt; &lt;/DataTemplate&gt; &lt;DataTemplate DataType="{x:Type local:BiologyQuestionViewModel}"&gt; &lt;local:BiologyQuestion /&gt; &lt;/DataTemplate&gt; &lt;/Window.Resources&gt; &lt;ItemsControl ItemsSource="{Binding QuestionViewModels}"&gt; &lt;ItemsControl.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;ContentControl Content="{Binding}" /&gt; &lt;/DataTemplate&gt; &lt;/ItemsControl.ItemTemplate&gt; &lt;/ItemsControl&gt; &lt;/Window&gt; </code></pre> <p><strong>Update</strong></p> <p>Kyle Tolle pointed out a nice simplification for setting <code>ItemsControl.ItemTemplate</code>. Here is the resulting code:</p> <pre><code>&lt;ItemsControl ItemsSource="{Binding QuestionViewModels}" ItemTemplate="{Binding}" /&gt; </code></pre>

    1. COLet's say the VM presents an ObservableCollection<Question>, would the runtime know to use the more specific data templates rather than the generic Question data template?

    2. CO@Quanta, yep, it should work fine. You just need to put the `ContentControl` into an `ItemsControl`.

    3. CO@Quanta, updated my answer to use an `ObservableCollection<QuestionViewModel>` and an `ItemsControl`.

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).
