How Can I Invoke A Server-side Event From Jquery (sharepoint 2010)?

In my Sharepoint 2010 app, I'm handling most events client-side with jQuery. However, for the saving of data to the Sharepoint list, and the generation of a PDF file with that data

Solution 1:

First of all, as far as I know, there is no such event for input type hidden in a ascx page. If you create the input type hidden with runat server in the ascx code then you'll see that when you try to add this event it's not available. However there are other events like OnClick that you can simulate to get the desired result.
