    <p>You have a couple of choices on how to achieve your goal. Either you can create a <code>Command</code> that opens the <code>ContextMenu</code>, then add a <code>KeyBinding</code> with the command and a <code>KeyGesture</code> of <code>ALT + CTRL</code> to the <code>InputBindings</code> of your main window.</p> <p>You can find out more about the <code>KeyBinding</code> class from the <a href="http://msdn.microsoft.com/en-us/library/system.windows.input.keybinding.aspx" rel="nofollow">KeyBinding Class</a> page and the <code>KeyGesture</code> class from the <a href="http://msdn.microsoft.com/en-us/library/system.windows.input.keygesture.aspx" rel="nofollow">KeyGesture Class</a> page at MSDN.</p> <p>The other option is to add a handler for the <code>PreviewMouseDown</code> (or similar) event and monitor whether the <code>ALT</code> and <code>CTRL</code> keys are being pressed, then programmatically launch the <code>ContextMenu</code> control if they are:</p> <pre><code>public void ListBox_PreviewKeyDown(object sender, KeyEventArgs e) { if ((e.KeyboardDevice.Modifiers &amp; ModifierKeys.Alt) == ModifierKeys.Alt &amp;&amp; (e.KeyboardDevice.Modifiers &amp; ModifierKeys.Control) == ModifierKeys.Control) { // Open ContextMenu } } </code></pre> <p>Now all that is left is to open the <code>ContextMenu</code> from code:</p> <pre><code>if (element.ContextMenu != null ) { element.ContextMenu.PlacementTarget = element; element.ContextMenu.IsOpen = true; } </code></pre> <p>If the <code>ContextMenu</code> is not placed correctly, you can set the placement using the <code>ContextMenu.HorizontalOffset</code> and <code>ContextMenu.HorizontalOffset</code> properties.</p>

    2. COI created a new WPF application based on your situation, added the code that I provided you with and the `ContextMenu` stays open for me after a key press without any problem... I don't know what your problem is, but if you really can't get it to stay open, then please add a new question here on StackOverflow... this one *has* been answered, so please mark it as so.

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.
