    <p>I'm fairly new to the Silverlight and the MVVM / Prism pattern so this may be a stupid question.</p> <p>I have a View which has custom controls within it. These custom controls are actually Views too and have ViewModels to drive them.</p> <p>Currently to add these 'child' Views to the View I'm using (see Fig.1) and then in the ViewModel I have an Initialise() method which resolves the child View and injects it (see Fig.2).</p> <p><strong>Fig.1</strong></p> <pre><code>&lt;UserControl x:Class="ProjectA.Module.Screens.Views.PlatformScreenView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Regions="clr-namespace:Microsoft.Practices.Composite.Presentation.Regions;assembly=Microsoft.Practices.Composite.Presentation" &gt; &lt;Grid x:Name="LayoutRoot"&gt; &lt;ContentControl Regions:RegionManager.RegionName="FeaturesSelectionControl" /&gt; &lt;/Grid&gt; </code></pre> <p></p> <p><strong>Fig.2</strong></p> <pre><code>public void Initialise() { IRegion featuresRegion = _regionManager.Regions["FeaturesSelectionControl"]; featuresRegion.Add(_container.Resolve&lt;IFeatureSelectionControlViewModel&gt;().View); } </code></pre> <p>My question is do I have to do this for every control I want to add? I understand why it works this way but it seems like quite a bit of code and also I need to keep track of all the region names and ensure I don't have any clashes etc. Is there a simpler way of doing this without regions and just in XAML?</p> <p>I've seen a snippet of XAML on StackOverflow <a href="https://stackoverflow.com/questions/1058124/how-can-i-bind-this-view-to-this-viewmodel">here</a> but not sure how it works and if it's what I want -</p> <pre><code>&lt;ContentControl Content="{Binding SmartFormViewModel}"/&gt; </code></pre> <p>Any help is much appreciated.</p> <p>James</p>

    2. COI've further edited my response after your other comment. I didn't realize your issue was with slightly smaller scope of parent and child views.

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.
