title: Operands of type Object used for '&'; runtime errors could occur
body: <p>When I set my code behind as "STRICT" (Option Strict On), I get the following error: <em>Operands of type Object used for '&amp;'; runtime errors could occur</em>. </p>
  
  <p>Here's the problematic line:</p>
  
  <pre><code>dataSet.Sort = CType(ViewState("sortExp") &amp; DESCENDING, String)
  </code></pre>
  
  <p>Just wanted to know what's wrong.
  Thanks</p>
