    <p>I wanted to solve this without needing to handle the listBoxItem double click event in the code-behind, and I didn't want to have to override the listBoxItem style (or define the style to override in the first place). I wanted to just fire a command when the listBox was doubleclicked.</p> <p>I created an attached property like so (the code is very specific, but you can generalise it as required):</p> <pre><code>public class ControlItemDoubleClick : DependencyObject { public ControlItemDoubleClick() { } public static readonly DependencyProperty ItemsDoubleClickProperty = DependencyProperty.RegisterAttached("ItemsDoubleClick", typeof(bool), typeof(Binding)); public static void SetItemsDoubleClick(ItemsControl element, bool value) { element.SetValue(ItemsDoubleClickProperty, value); if (value) { element.PreviewMouseDoubleClick += new MouseButtonEventHandler(element_PreviewMouseDoubleClick); } } static void element_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e) { ItemsControl control = sender as ItemsControl; foreach (InputBinding b in control.InputBindings) { if (!(b is MouseBinding)) { continue; } if (b.Gesture != null &amp;&amp; b.Gesture is MouseGesture &amp;&amp; ((MouseGesture)b.Gesture).MouseAction == MouseAction.LeftDoubleClick &amp;&amp; b.Command.CanExecute(null)) { b.Command.Execute(null); e.Handled = true; } } } public static bool GetItemsDoubleClick(ItemsControl element) { return (bool)element.GetValue(ItemsDoubleClickProperty); } </code></pre> <p>}</p> <p>I then declare my ListBox with the attached property and my target command:</p> <pre><code>&lt;ListBox ItemsSource="{Binding SomeItems}" myStuff:ControlItemDoubleClick.ItemsDoubleClick="true"&gt; &lt;ListBox.InputBindings&gt; &lt;MouseBinding MouseAction="LeftDoubleClick" Command="MyCommand"/&gt; &lt;/ListBox.InputBindings&gt; &lt;/ListBox&gt; </code></pre> <p>Hope this helps.</p>

    1. CObut won't that fire if they double click on the scroll bar? Or any padding between ListBoxItems?

    2. COYes, it will fire if you double click anywhere in the list box. Still for me it is a good solution, I like it that it does not take code behind. Changed the command parameters for b.Command.CanExecute(null) and Execute(null) from null to b.CommandParameter.

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).
