title: wpf Listbox giving columns a header
body: <p>I have the following markup (xaml):</p>
  
  <pre><code>&lt;ListBox Name="lbEurInsuredType" HorizontalContentAlignment="Stretch"&gt;
              &lt;ListBox.ItemTemplate&gt;
                 &lt;DataTemplate&gt;
                      &lt;Grid Margin="0,2"&gt;
                          &lt;Grid.ColumnDefinitions&gt;
                          &lt;ColumnDefinition Width="100"&gt;&lt;/ColumnDefinition&gt;
                              &lt;ColumnDefinition Width="30"&gt;&lt;/ColumnDefinition&gt;&lt;ColumnDefinition Width="2"&gt;&lt;/ColumnDefinition&gt;
                              &lt;ColumnDefinition Width="30"&gt;&lt;/ColumnDefinition&gt;
                     &lt;/Grid.ColumnDefinitions&gt;
                     &lt;TextBlock Text="{Binding Title}"&gt;&lt;/TextBlock&gt;
                     &lt;TextBox Text="{Binding Uw}" Grid.Column="1"&gt;&lt;/TextBox&gt;
                     &lt;TextBox Text="{Binding Partner}" Grid.Column="3"&gt;&lt;/TextBox&gt;
                  &lt;/Grid&gt;
              &lt;/DataTemplate&gt;&lt;/ListBox.ItemTemplate&gt;
  
          &lt;/ListBox&gt;
  </code></pre>
  
  <p>This all looks ok, but now above column 1 and 3 I want to place a header. Can anyone show me how I add headers to my two columns.</p>
