title: Show partition around each item of longlistselector in wp8
body: <p>I want to show partition around each item of longlistselector like listview in android. I am unable to find any relevant data. All people are showing data without showing partition line etc.</p>
  
  <pre><code>&lt;phone:LongListSelector x:Name="playerList"
                  IsGroupingEnabled="False" LayoutMode="List" VerticalAlignment="Top" HorizontalAlignment="Center"
                           Width="446"&gt;
              &lt;phone:LongListSelector.ItemTemplate&gt;
                  &lt;DataTemplate&gt;
                      &lt;TextBlock Text="{Binding info}" /&gt;
                  &lt;/DataTemplate&gt;
              &lt;/phone:LongListSelector.ItemTemplate&gt;
  
      &lt;/phone:LongListSelector&gt;
  </code></pre>
