title: Callback after __doPostBack()?
body: <p>I am refreshing an UpdatePanel with Javscript by calling a method like so:</p>
  
  <pre><code>reloadDropDown = function (newValue)
  {
    __doPostBack("DropDown1", "");
    selectNewValueInDropDown(newValue);
  }
  </code></pre>
  
  <p>Inside my UpdatePanel is a <code>&lt;select&gt;</code> box that I need to select an <code>&lt;option&gt;</code> with a <strong>newValue</strong>.  My problem is that my <code>selectNewValueInDropDown</code> method is being called prior to the <code>__doPostBack</code> from completing.  Is there a way I can "wait" for the postback before calling my <code>selectNewValueInDropDown</code> method?</p>
