title: WPF Tooltip Binding
body: <p>I am only two weeks into WPF so this is probably a trivial question.  I have a collection "CellList" which has a few properties I would like to bind to a <code>ToolTip</code> so when I hover over a label information from the current instance of <code>CellList</code> is displayed.  How do I do that?  I understand simple binding and this maybe simple binding too but I can't wrap my head around it.  Below is my XAML for the label.  Could someone explain to me how I can accomplish this.</p>
  
  <pre><code>&lt;HierarchicalDataTemplate&gt;
        &lt;ListBox ItemsSource="{Binding CellList}"&gt;
             &lt;ListBox.ItemTemplate&gt;
                 &lt;DataTemplate&gt;
                   &lt;Label Content=" " Height="20" Width="15" Background="{Binding Path=ExptNameBkg, Converter={StaticResource ExptNameToBrushConverter}}"                                                   BorderBrush="Black" BorderThickness="1" &gt;
                    &lt;/Label&gt;  
                &lt;/DataTemplate&gt;                                    
              &lt;/ListBox.ItemTemplate&gt;   
         &lt;/ListBox&gt;
  &lt;/HierarchicalDataTemplate&gt;
  </code></pre>
  
  <p>Thanks.</p>
