    <p>I am writing an application, WPF, using PRISM. I'm new so apologies if this question is poor form:</p> <p>I have a module that up to now has a user control for displaying a list of inspections. My module has entities written and a DbContext class to access DB. My question is where should this get initialsed and passed into my ViewModel???????</p> <p>Shell XAML</p> <pre><code>&lt;Window x:Class="ChargeMgm.Desktop.Shell" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:prism="http://www.codeplex.com/prism" Title="EMS" Height="350" Width="525"&gt; &lt;Grid&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="auto"/&gt; &lt;RowDefinition MinHeight="100"/&gt; &lt;RowDefinition/&gt; &lt;/Grid.RowDefinitions&gt; &lt;TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" FontFamily="Calibri" FontSize="16" Foreground="SteelBlue" Margin="5"&gt;Street Works Modules&lt;/TextBlock&gt; &lt;Border BorderThickness="1" BorderBrush="SteelBlue" CornerRadius="3" Grid.Row="1" Margin="5"&gt; &lt;ItemsControl prism:RegionManager.RegionName="MainRegion" VerticalContentAlignment="Stretch" HorizontalContentAlignment="Stretch"/&gt; &lt;/Border&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>Bootstrapper class</p> <pre><code> class Bootstrapper : UnityBootstrapper { protected override System.Windows.DependencyObject CreateShell() { return new Shell(); } protected override void InitializeShell() { base.InitializeShell(); App.Current.MainWindow = (Window)this.Shell; App.Current.MainWindow.Show(); } protected override void ConfigureModuleCatalog() { base.ConfigureModuleCatalog(); ModuleCatalog moduleCatalog = (ModuleCatalog)this.ModuleCatalog; moduleCatalog.AddModule(typeof(DefectModule.DefectModule)); } } </code></pre> <p>Module</p> <pre><code>public class DefectModule : IModule { private readonly IRegionManager regionManager; private IUnityContainer container; public DefectModule(IUnityContainer container, IRegionManager regionManager) { this.regionManager = regionManager; this.container = container; } public void Initialize() { container.RegisterType&lt;IDefectsView, DefectsView&gt;(); container.RegisterType&lt;IDefectsViewModel, DefectsViewModel&gt;(); container.RegisterType&lt;IDefectContext, DefectContext&gt;(); var view = container.Resolve&lt;IDefectsView&gt;(); if(regionManager.Regions.ContainsRegionWithName("MainRegion")) { regionManager.Regions["MainRegion"].Add(view); //regionManager.RegisterViewWithRegion("MainRegion", typeof(IDefectsView)); } } } </code></pre>

    1. COWhat do you mean by initialised? If you're using Prism what dependency container are you using (Unity or MEF)?

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.

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