    <p>I've just recently started working on an app that displays a bunch of xml data in a listBox, but the problem is not every xml item has a child value (In my problem, upload), so its listBox code shouldn't be displayed.</p> <p>Example:</p> <pre><code>&lt;item&gt; &lt;id&gt;1&lt;/id&gt; &lt;body&gt;Some text&lt;/body&gt; &lt;upload&gt;&lt;/upload&gt; &lt;created&gt;Some text&lt;/created&gt; &lt;/item&gt; </code></pre> <p>I'm getting the data and populating my list this way:</p> <pre><code>var data = from query in loadedData.Descendants("item") select new droppedItem { Id = (int)query.Element("id"), Body = (string)query.Element("body"), Upload = (string)query.Element("upload"), Created = (DateTime)ConvertFromUnixTimestamp((double)query.Element("created")) }; userDrops.ItemsSource = data; </code></pre> <p>And my xaml looks like:</p> <pre><code>&lt;ListBox Margin="0,0,-12,0" Name="userDrops"&gt; &lt;ListBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;StackPanel Margin="0,0,0,17" Width="432"&gt; &lt;RichTextBox&gt; &lt;Paragraph&gt; &lt;Run Text="{Binding Body}" FontSize="25" FontFamily="Segoe WP"&gt;&lt;/Run&gt; &lt;/Paragraph&gt; &lt;Paragraph&gt; &lt;Hyperlink NavigateUri="{Binding Upload}" TargetName="_blank" FontSize="25" FontFamily="Segoe WP"&gt;{Binding Upload}&lt;/Hyperlink&gt; &lt;/Paragraph&gt; &lt;Paragraph&gt; &lt;Run Text="{Binding Created}" FontFamily="Segoe WP SemiLight"&gt;&lt;/Run&gt; &lt;/Paragraph&gt; &lt;/RichTextBox&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;/ListBox.ItemTemplate&gt; &lt;/ListBox&gt; </code></pre> <p>What I want to do is only display the paragraph holding the upload info if the xml upload child holds a value. Otherwise, just remove it from the listBox. I can't figure out how to change the basic listBox template though.</p> <p>Any help would be great!</p>

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.
