title: jQuery call __doPostBack on LinkButton
body: <p>I have a LinkButton that I need to perform a click on to cause a postback. The actual link target is:</p>
  
  <p><code>javascript:__doPostBack('ctl00$c1$btnRefreshGrid','');</code></p>
  
  <p>Clicking the link does perform the postback, as verified by a breakpoint in the code-behind. Also pasting <code>javascript:__doPostBack('ctl00$c1$btnRefreshGrid','')</code> in the address bar of the browser works with the same effect.</p>
  
  <p>I've tried the following with no effect at all:</p>
  
  <pre><code>__doPostBack('ctl00$c1$btnRefreshGrid','');    
  $('#ctl00$c1$btnRefreshGrid').click();
  $('#ctl00$c1$btnRefreshGrid').trigger('click');
  eval($('#ctl00$c1$btnRefreshGrid').attr("href"));
  </code></pre>
  
  <p>I've tried using both <code>&lt;%= btnRefreshGrid.UniqueID %&gt;</code> and <code>&lt;%= btnRefreshGrid.ClientID %&gt;</code> to generate the selector.</p>
