title: Access parent data in a nested strongly typed repeater
body: <p>Lets say I have a class structure that looks something like this:</p>
  
  <pre><code>public class A
  {
      public string Poperty1 { get; set; }
      public string Poperty2 { get; set; }
      public List&lt;B&gt; Property3 { get; set; }
  }
  
  public class B
  {
      public string Property4 { get; set; }
      public string Property5 { get; set; }
  }
  </code></pre>
  
  <p>...and a couple of nested repeaters that look like this:</p>
  
  <pre><code>&lt;asp:Repeater ItemType="A" runat="server"&gt;
      &lt;ItemTemplate&gt;
          &lt;asp:Label Text="&lt;%# Item.Property1 %&gt;" runat="server" /&gt;
          &lt;asp:Repeater runat="server" DataSource="&lt;%# Item.Property3 %&gt;" ItemType="B"&gt;
              &lt;ItemTemplate&gt;
                  &lt;asp:Label Text="&lt;%# Item.Property4 %&gt;" runat="server" /&gt;
              &lt;/ItemTemplate&gt;
          &lt;/asp:Repeater&gt;
      &lt;/ItemTemplate&gt;
  &lt;/asp:Repeater&gt;
  </code></pre>
  
  <p>How would I access Property2 from the second repeater?</p>
