How to use jquery to notify ASP an event has happened

[Ponzano Paolo]

Hello to everybody, I'm currently developing a 2 level menu using jQuery... I load data from a Webservice and populate the toplevel item and sublevelitems... my webapplication is made of ascx and I've got a main page that load the ascx, I was wondering if there's a way using jQuery to notify the server that a menu item has been clicked ( I tried creating an ajax asp.net server control menu but got lost, so I moved to jQuery)... Thanks in advance Paolo
