auto partial page refresh in asp.net without UpdatePanel <p>I want to make auto partial page refresh in asp.net. There is UpdatePanel but it sends too much data. So I've found that I can make a webservice and call it by the JavaScript code. But I don't know how to call webservice automatic. There are many examples showing how to call webservice by the button click event:</p> <p><a href="http://www.asp.net/ajax/videos/how-do-i-make-client-side-network-callbacks-with-aspnet-ajax" rel="nofollow">http://www.asp.net/ajax/videos/how-do-i-make-client-side-network-callbacks-with-aspnet-ajax</a></p> <p>How to do this by the interval? Am I going in good direction?</p>
