    <p>I have worked through the answer provided <a href="https://stackoverflow.com/questions/1025011/add-hyperlink-to-automatically-generated-xml-in-silverlight-c">here</a>. I have been able to create a list of automatically generated Hyperlink buttons in a ListBox. The goal is that, when a different user is typed into the box and the button is clicked, they old artists are removed (assuming it's a valid username) and replaced with the artists from the new last.fm user. However, now this line does not work:</p> <pre><code>ArtistsList.Items.Clear(); </code></pre> <p>Is this only for text? If so, does anybody know another way to remove the hyperlink buttons once the Go! button has been clicked again? I'll provide what I believe to be the pertinent page.xaml.cs code if that will help.</p> <pre><code> if (uname.Text != String.Empty &amp;&amp; uname.Text != "Try Another One!") { App app = (App)Application.Current; app.UserName = uname.Text; String getTopArtists = "http://ws.audioscrobbler.com/2.0/?method=user.gettopartists&amp;user=" + app.UserName + "&amp;api_key=d2d620af554a60f228faed8d502c4936"; WebClient web = new WebClient(); WebClient client = new WebClient(); client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(DownloadStringCompleted); client.DownloadStringAsync(new Uri(getTopArtists)); } </code></pre> <p>This is what the HyperlinkButton looks like in the page.xaml code:</p> <pre><code>&lt;ListBox FontFamily="Calibri" HorizontalAlignment="Center" VerticalAlignment="Center" Width="200" Height="200" Margin="50,140,50,50" x:Name="ArtistsList" Foreground="Crimson"&gt; &lt;ListBox.ItemTemplate&gt; &lt;DataTemplate&gt; &lt;StackPanel&gt; &lt;HyperlinkButton Content="{Binding Name}" NavigateUri="{Binding Amazon}" TargetName="_blank" Width="173.5" Foreground="Crimson"&gt;&lt;/HyperlinkButton&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;/ListBox.ItemTemplate&gt; &lt;/ListBox&gt; </code></pre> <p>I believe this is all of the necessary code to answer the question. If not, I can provide more.</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.
