title: Pass binded object directly into DataTemplate item
body: <p>I Have a collection <code>Items</code> of <code>JSection</code> objects that I pass to <code>LongListMultiSelector</code>. I would like to directly pass every <code>JSection</code> into each <code>controls:Section</code>. How can I do that?</p>
  
  <p>XAML that causes runtime exception:  </p>
  
  <pre><code>&lt;toolkit:LongListMultiSelector ItemsSource="{Binding Items}"&gt;
      &lt;toolkit:LongListMultiSelector.ItemTemplate&gt;
          &lt;DataTemplate&gt;
              &lt;controls:Section Data="{Binding}" /&gt;
          &lt;/DataTemplate&gt;
      &lt;/toolkit:LongListMultiSelector.ItemTemplate&gt;
  &lt;/toolkit:LongListMultiSelector&gt;
  </code></pre>
  
  <p>UserControl that contains XAML with <code>LongListMultiSelector</code>:</p>
  
  <pre><code>namespace Controls
  {
      public partial class RemoteHomePage : UserControl
      {
          public ObservableCollection&lt;JSection&gt; Items { get; set; }
  
          public RemoteHomePage()
          {
              Items = new ObservableCollection&lt;JSection&gt; { };
  
              Items.Add(new JSection { id = 2, name = "Section 2" });
              Items.Add(new JSection { id = 1, name = "Section 1" });
              Items.Add(new JSection { id = 3, name = "Section 3" });
  
              InitializeComponent();
          }
      }
  }
  </code></pre>
  
  <p><code>Section</code> class:  </p>
  
  <pre><code>namespace Controls
  {
      public partial class Section : UserControl
      {
          public JSection Data { get; set; }
  
          public Section()
          {
              InitializeComponent();
          }
      }
  }  
  </code></pre>
