    <p>To answer a little more conceptually:</p> <p><a href="http://msdn.microsoft.com/en-us/library/system.windows.controls.primitives.selector.selectedvaluepath.aspx" rel="noreferrer"><code>SelectedValuePath</code></a> defines which property (by its name) of the objects bound to the ListBox's <code>ItemsSource</code> will be used as the item's <code>SelectedValue</code>.</p> <p>For example, if your ListBox is bound to a collection of <code>Person</code> objects, each of which has <code>Name</code>, <code>Age</code>, and <code>Gender</code> properties, <code>SelectedValuePath=Name</code> will cause the value of the selected <code>Person</code>'s <code>Name</code> property to be returned in <code>SelectedValue</code>.</p> <p><em>Note that if you override the ListBox's ControlTemplate (or apply a Style) that specifies what property should display, <code>SelectedValuePath</code> cannot be used.</em></p> <p><code>SelectedItem</code>, meanwhile, returns the entire <code>Person</code> object currently selected. </p> <p>(Here's <a href="http://msdn.microsoft.com/en-us/library/ms788714.aspx" rel="noreferrer">a further example from MSDN</a>, using TreeView)</p> <p><strong><em>Update:</strong> As @Joe pointed out, the DisplayMemberPath property is unrelated to the Selected* properties. Its proper description follows:</em></p> <p>Note that these values are distinct from <code>DisplayMemberPath</code> (which is defined on ItemsControl, not Selector), but that property has similar behavior to <code>SelectedValuePath</code>: in the absence of a style/template, it identifies which property of the object bound to item should be used as its string representation.</p>

    1. COThis is wrong. `DisplayMemberPath` defines the property that will be used to display the selected item (as well as other items). `SelectedValuePath` is the path to the property of the `SelectedItem` that is returned by the `SelectedValue` property - as you correctly state in the fifth paragraph - but has nothing to do with what is displayed.

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).
