title: Select2 JQuery issue with ASP.NET UpdatePanel
body: <p>Have a existing solution I have been asked to enhance with Select2 JQuery library.</p>
  
  <p>Have an <code>updatepanel</code> with a save button.  On that <code>updatepanel</code> is a ASP.NET <code>DropDownList</code>.</p>
  
  <p>on document ready I issue</p>
  
  <pre><code>$('.dropdownspecificclass').select2();
  </code></pre>
  
  <p>When page first renders it looks as expected the <code>DropDownList</code> has that tags view that Select2 provides.</p>
  
  <p>Click the save button and the save process is done <strong><em><code>async</code></em></strong> without a page refresh, but the Select2 dropdown list loses it Select2 styling and now just looks like a regular dropdown.  </p>
  
  <p>If I try to apply the Select2 class to the CssClass property of the control then a JavaScript error occurs on the client. "<em>Uncaught query function not defined for Select2 selectControlName</em>"</p>
  
  <p>Thoughts?</p>
