In this article I will provide solution to jQuery Plugins not working after UpdatePanel’s Asynchronous request or Partial PostBack is completed.
 
 
Cause
All jQuery plugins are applied on the Page Load event of the HTML Page or in other words document ready event which is fired when the whole page or document is rendered completely in browser. Now jQuery assigns a unique identification to all controls when applying the plugin. But when some control is inside UpdatePanel and a Partial PostBack occurs the Unique Ids assigned by jQuery is lost and hence the plugin stops working.
 
 
Solution
The solution to this problem is that we need to re-apply the jQuery Plugin every time the UpdatePanel’s Asynchronous request or Partial PostBack is completed. For which we can make use of the event handlers provided by the ASP.Net Framework to detect completion of UpdatePanel’s Asynchronous request or Partial PostBack.
 
You will notice that first the Accordion and Tabs jQuery Plugins are applied in the document ready event handler and then the same plugins are re-applied in the ASP.Net UpdatePanel endRequest event handler. Hence in-spite of UpdatePanel Refresh the jQuery plugins will always work.
