title: WPF Combobox: Different template in textbox and drop-downlist
body: <p>This is my combo-box.</p>
  
  <pre><code>    &lt;ComboBox Height="45" HorizontalAlignment="Left" Margin="184,66,0,0" Name="ComboBox1" VerticalAlignment="Top" Width="216"&gt;
          &lt;ComboBox.ItemTemplate&gt;
              &lt;DataTemplate&gt;
                  &lt;StackPanel Orientation="Horizontal"&gt;
                      &lt;Label Content="{Binding FullName}" Width="150" /&gt;
                      &lt;Label Content="{Binding Title}" Width="100"/&gt;
                      &lt;Label Content="{Binding BranchName}" /&gt;
                  &lt;/StackPanel&gt;
              &lt;/DataTemplate&gt;
          &lt;/ComboBox.ItemTemplate&gt;
      &lt;/ComboBox&gt;
  </code></pre>
  
  <p>How can I change it so that only the FullName appears in the textbox portion of the combobox while all three columns still appear in the drop-down portion?</p>
