    <p>Thanks Jobi. That's pretty clever. The rabbit hole of WPF keeps getting deeper and deeper.</p> <p>Here is what I did based on your suggestion:</p> <pre><code>private void Expander_Expanded(object sender, RoutedEventArgs e) { DependencyObject dep = (DependencyObject)sender; while ((dep != null) &amp;&amp; !(dep is ListBoxItem)) { dep = VisualTreeHelper.GetParent(dep); } if (dep == null) return; int index = PersonList.ItemContainerGenerator.IndexFromContainer(dep); PersonList.SelectedIndex = index; } private void Expander_Collapsed(object sender, RoutedEventArgs e) { DependencyObject dep = (DependencyObject)sender; while ((dep != null) &amp;&amp; !(dep is ListBoxItem)) { dep = VisualTreeHelper.GetParent(dep); } if (dep == null) return; int index = PersonList.ItemContainerGenerator.IndexFromContainer(dep); if (PersonList.SelectedIndex == index) PersonList.SelectedIndex = -1; } </code></pre> <p>I had to change the ListViewItem to ListBoxItem (I was using a ListBox).</p> <p>Also, I used the index to select or de-select the ListBox.SelectedIndex. This give me the experience I was looking for. </p> <ol> <li><p>The first time someone expands an Expander, it selects the newly expanded ListBoxItem.</p></li> <li><p>If someone expands another Expander, the previous ListBoxItem is deselected, but remains expanded, the newly expanded ListBoxItem is selected.</p></li> <li><p>If someone collapses a selected Expander, the ListBoxItem is deselected.</p></li> <li><p>If there are several Expanders expanded, someone collapses a non-selected ListBoxItem expander, the previously selected ListBoxItem remains selected.</p></li> </ol> <p>Thanks for the help - I think this is a very useful little code snippet for anyone who uses Expanders in a ListBox.</p>

    1. COcool.. Yeah not just expander in a Listbox's DataTemplate.. Any control like Button/checkbox or anything you really need this kind of a hack.

    2. COI think your word "hack" is more appropriate then my work "code snippet". This solution above is not very pretty - it works - but not pretty. There should be a more elegant solution then walking the visual graph.

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.
