title: Windows phone how to get data from Button.content
body: <p>I have listbox like this:</p>
  
  <pre><code>&lt;ListBox Height="589" HorizontalAlignment="Left" Name="AllNotesListBox" VerticalAlignment="Top" Width="460" SelectionChanged="AllNotesListBox_SelectionChanged"&gt;
      &lt;ListBox.ItemTemplate&gt;
          &lt;DataTemplate&gt;
              &lt;Button Width="460" Height="150" DoubleTap="Button_DoubleTap"&gt;
                  &lt;Button.Content&gt;
                      &lt;StackPanel Width="460" Orientation="Horizontal" Height="120"&gt;
                          &lt;Image Source="/SimpleNote;component/Images/note.png" Width="60" Height="60"&gt;&lt;/Image&gt;
                          &lt;!--&gt;Code for title looks&lt;--&gt;
                          &lt;StackPanel Orientation="Horizontal" Height="80"&gt;
                              &lt;TextBlock Text="Title: "&gt;&lt;/TextBlock&gt;
                              &lt;TextBlock Text="{Binding title}"&gt;&lt;/TextBlock&gt;
                          &lt;/StackPanel&gt;               
                      &lt;/StackPanel&gt;
                  &lt;/Button.Content&gt;
              &lt;/Button&gt;
          &lt;/DataTemplate&gt;
      &lt;/ListBox.ItemTemplate&gt;
  &lt;/ListBox&gt;
  </code></pre>
  
  <p>And now in function <code>Button_DoubleTap</code> I want to have <code>title</code> that is on the button that user clicked. How I can do that?</p>
