title: how to trigger updatepanel within a javascript function
body: <p>i have an updatepanel in my asp.net web page. I want to trigger the updatepanel within a javascript function insead of triggering with a button. <br>
  In order to do that, i used <code>__doPostBack('myUpdatePanel', '');</code> function. But i think it causes the whole page postback. My document.ready function is also executed when i call this function. I may be missing some points. <br>
  Is there any other way to trigger updatepanel within a javascript function?</p>
