    <p>There is a listbox with the following ItemContainerStyle, it's binding to the ViewModel class but when scroll the listbox its performance not smooth. I check this on the web, and I replaced the visualstackpanel with normal stackpanel in the listbox. Yes, it scrolls smoothly, but it freezes when the data is loading. Is there anything I can do?</p> <pre><code> &lt;Style TargetType="ListBoxItem" x:Key="ListBoxItem"&gt; &lt;Setter Property="Background" Value="Transparent"/&gt; &lt;Setter Property="BorderThickness" Value="0" /&gt;

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.
