title: panorama + listbox, wp7, text is truncated and scrolling does not work
body: <p>i am using a Panorama control. inside each PanoramaItem, i have a ListBox. the ListBox holds a bunch of TextBlock; the reason is because i am displaying very long text and from another post, i found out that wp7 has limitations when displaying long text. </p>
  
  <p>for example, i have two objects defined as follows.</p>
  
  <pre><code>public class TextItem {
   public string Text { get; set; }
  }
  
  public class DisplayItem {
   public string Header { get; set; }
   public string FullHeader { get; set; }
   public List&lt;TextItem&gt; TextItems { get; set; }
  }
  </code></pre>
  
  <p>my xaml to bind to a List&lt;DisplayItem&gt; is as follows.</p>
  
  <pre><code>&lt;controls:Panorama ItemsSource="{Binding}"&gt;
   &lt;controls:Panorama.HeaderTemplate&gt;
    &lt;DataTemplate&gt;
     &lt;TextBlock Text="{Binding Header}" TextWrapping="Wrap"/&gt;
    &lt;/DataTemplate&gt;
   &lt;/controls:Panorama.HeaderTemplate&gt;
   &lt;controls:Panorama.ItemTemplate&gt;
    &lt;DataTemplate&gt;
     &lt;StackPanel Orientation="Vertical"&gt;
      &lt;TextBlock Text="{Binding FullHeader}" TextWrapping="Wrap"/&gt;
      &lt;ListBox ItemsSource="{Binding TextItems}"&gt;
       &lt;ListBox.ItemTemplate&gt;
        &lt;DataTemplate&gt;
         &lt;TextBlock Text="{Binding Text}"/&gt;
        &lt;/DataTemplate&gt;
       &lt;/ListBox.ItemTemplate&gt;
     &lt;/StackPanel&gt;
    &lt;/DataTemplate&gt;
   &lt;/controls:Panorama.ItemTemplate&gt;
  &lt;/controls:Panorama&gt;
  </code></pre>
  
  <p>all the data bind properly, however, when i attempt to scroll the ListBox, it stops without ever going all the way to the bottom. the effect is to me is that "scrolling isn't working" and "text is truncated." </p>
  
  <p>any idea on what i am doing wrong?</p>
  
  <p>as a side note, i also posted a question on displaying very long text (i.e. an end-user license agreement EULA). a user responded by giving me a link to a control he made to display very long text. the post is at <a href="https://stackoverflow.com/questions/6602544/how-many-characters-can-a-silverlight-textblock-hold">how many characters can a Silverlight TextBlock hold?</a>. when i use that control and/or approach to store my long text, i get the same effect. </p>
