title: C# MultiColumn Listbox
body: <p>I have two the following code</p>
  
  <pre><code>    List&lt;string&gt; _items = new List&lt;string&gt;();
      List&lt;string&gt; _items2 = new List&lt;string&gt;();
  </code></pre>
  
  <p>I want to add both of them into a single multi-column Listbox</p>
  
  <p>Column1 could be _items whereas Column2 can be _items2</p>

  <p>I've added _items to the Listbox by</p>
  
  <pre><code>Listbox1.DataSource = _items
  </code></pre>
  
  <p>Thank you</p>
