Looking to implement auto partial page refresh in asp.net without sending excessive data through UpdatePanel. Considering using a webservice called by JavaScript instead, but unsure how to trigger it automatically rather than by button click event.
Many examples demonstrate calling a webservice on button click, like the one here: http://www.asp.net/ajax/videos/how-do-i-make-client-side-network-callbacks-with-aspnet-ajax
How can I achieve this using intervals? Is this the right approach?
