    <p>As you have noticed the <a href="http://msdn.microsoft.com/en-us/library/system.windows.input.routedcommand.aspx" rel="noreferrer"><code>RoutedCommand</code> class</a> is an implementation of the <code>ICommand</code> interface, its main distinction if that its function is similar to that of a <code>RoutedEvent</code>:</p> <blockquote> <p>The Execute and CanExecute methods on a RoutedCommand do not contain the application logic for the command as is the case with a typical ICommand, but rather, these methods raise events that traverse the element tree looking for an object with a CommandBinding. The event handlers attached to the CommandBinding contain the command logic.</p> <p>The Execute method raises the PreviewExecuted and Executed events. The CanExecute method raises the PreviewCanExecute and CanExecute events.</p> </blockquote> <p>In a case when you don't want the behavior of the <code>RoutedCommand</code> you'll be looking at your own implementation of <code>ICommand</code>. As for the MVVM pattern I can't say that one solution, it seems that everyone has their own methodology. However, here are a few approaches to this problem that I've come across:</p> <ul> <li><a href="http://www.codeproject.com/KB/WPF/VMCommanding.aspx" rel="noreferrer">Using RoutedCommands with a ViewModel in WPF</a></li> <li><a href="http://msdn.microsoft.com/en-us/magazine/dd419663.aspx#id0090030" rel="noreferrer">Relaying Command Logic</a></li> <li><a href="http://marlongrech.wordpress.com/2008/11/26/avoiding-commandbinding-in-the-xaml-code-behind-files/" rel="noreferrer">Simple Command</a> (almost identical to Relay Command but worth reading)</li> </ul>

    2. COThank you. I think the most important think to realize is that they traverse the tree looking for an object with CommandBinding. As in MVVM I want to avoid CommandBindings, I decide for ICommand.

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).
