    <p>Use CommandParameter. Using <code>{Binding}</code> will pass the object in the observable collection that was clicked. More at <a href="http://msdn.microsoft.com/en-us/library/ms752308.aspx#creating_commands" rel="nofollow">MSDN</a> </p> <pre><code>&lt;Button Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.OpenSessionCommand}" CommandParemeter="{Binding}" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Width="243" Height="42"&gt; &lt;TextBlock TextWrapping="Wrap"&gt; &lt;Run Text="{Binding SessionName}"/&gt;&lt;LineBreak/&gt; &lt;Run Text="{Binding Genre}"/&gt;&lt;Run Text=" - "/&gt; &lt;Run Text="{Binding Tempo}"/&gt; &lt;/TextBlock&gt; &lt;/Button&gt; </code></pre> <p>You will also need to adjust the OpenSessionCommand method signature to accept your parameter but that will depend on what Command implementation you are using.</p> <p><strong>UPDATE</strong></p> <p>Below is a generic implementation of DelegateCommand that accepts a parameter.</p> <pre><code>public class DelegateCommand&lt;T&gt; : ICommand where T : class { private readonly Action&lt;T&gt; _command; private readonly Func&lt;T, bool&gt; _canExecute; public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } public DelegateCommand(Action&lt;T&gt; command, Func&lt;T, bool&gt; canExecute = null) { if (command == null) throw new ArgumentNullException(); _canExecute = canExecute; _command = command; } public void Execute(object parameter) { _command(parameter as T); } public bool CanExecute(object parameter) { return _canExecute == null || _canExecute(parameter as T); } } </code></pre> <p>Now when you define your ICommand it should be something like this:</p> <pre><code> public ICommand OpenSessionCommand { get { return new DelegateCommand&lt;Button&gt;(OpenSession); } } public void OpenSession(Button button) { ContinueReceiving = false; dispatcherTimer.Stop(); Messenger.Default.Send&lt;NavigateMessage&gt;(new NavigateMessage(SessionViewModel.ViewName, this)); } </code></pre>

    1. COI updated my question with my implementation of DelegateCommand. I see what you mean when I add a breakpoint over "Executed" - I see that item passed in as parameted. How do I get that to OpenSession() ?

    2. COOpenSession will automatically have the parameter. When you create the canexecute and execute define them as (o) => Button b = o as Button (as an example).

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).
