Hi Jerry,

I'm not sure if you've seen the official documentation of AJAX here:

#ASP.NET AJAX > Web Services > Exposing Web Services to Client Script
http://asp.net/ajax/documentation/live/tutorials/ExposingWebServicesToAJAXTu
torial.aspx

Of course the tutorial only explained some basic usage of this.

Dino Esposito has once written an article in MSDN Magazine on the topic
about "Page Methods vs. Web Service Methods" which I think is quite good:

#Cutting Edge: Perspectives on ASP.NET AJAX -- MSDN Magazine, February 2007
http://msdn.microsoft.com/msdnmag/issues/07/02/CuttingEdge/default.aspx#S5

Please feel free to let me know if you have any other questions. Thanks.

Regards,
