Masterpages, body onload-event and calling a server function

Hi!

I tried in the "Discussion & Suggestions", but I guess this is the more appropriate forum to ask this question.

I'm using Master Pages in my app. I have ONE page where I need to add a body onload-event on the client side, that will call a server-side function, which will enable timers that are placed in the UpdatePanel on the page. The reason it has to be done in the body onload-event is that I need the page the be fully loaded on the client side, with pictures and everything, before enabling the timer that will update certain fields on the page.

So my questions are:



How do I add a client side body onload-event to a page with a MasterPage, since there is no body-tag in the page, only in the Master Page?

How do I in that onload-event call a server-side function which would enable the timers? I guess it will have something to do with enabling PageMethods and defining the function as a WebSe ...
