    <p><strong>Grid example with the trigger:</strong></p> <pre><code>&lt;Grid x:Name="LayoutRoot" DataContext="{Binding ProjectGrid, Source={StaticResource Locator}}"&gt; &lt;i:Interaction.Triggers&gt; &lt;i:EventTrigger EventName="Loaded"&gt; &lt;GalaSoft_MvvmLight_Command:EventToCommand Command="{Binding LoadedCommand, Mode=OneWay}" PassEventArgsToCommand="True"/&gt; &lt;/i:EventTrigger&gt; &lt;/i:Interaction.Triggers&gt; </code></pre> <p><strong>In my ViewModel I set the LoadedCommand like this:</strong></p> <pre><code>public RelayCommand&lt;RoutedEventArgs&gt; LoadedCommand {get;private set;} </code></pre> <p><strong>And in the ViewModel initializer I have this:</strong></p> <pre><code>public ProjectGridViewModel() { LoadedCommand = new RelayCommand&lt;RoutedEventArgs&gt;(e =&gt; { this.DoLoaded(e); } ); } </code></pre> <p><strong>Then, in my DoLoaded I'm trying to do this:</strong></p> <pre><code>Grid _projectGrid = null; public void DoLoaded(RoutedEventArgs e) { _projectGrid = e.OriginalSource as Grid; } </code></pre> <p>You can see I'm trying to get rid of my Loaded="" in my Grid in my view, and do a RelayCommand instead. <strong>The issue is the OriginalSource brings back nothing.</strong> My loaded event is running nice this way, but I need to get the Grid in via the RoutedEventArgs it seems.</p> <p>I tried passing in the Grid in the EventCommand with CommandParameter="{Binding ElementName=LayoutRoot}", but this just crashes VS2010 when hitting F5 and running the project.</p> <p>Any ideas? Or a better way to do this? I had the Loaded event run in the views C# then call the ViewModel in the Views code-behind, but I'd like to do a nicer binding. Talking to the ViewMode in the Views code-behind feels like a hack.</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.
