Accessing the pages server controls during webmethod calback

Hi,

Tell me please, when we call a webmethod during a callback, we send parameters through the javascript and dom to the webmethod on the server, right?

What if on the server I want, not only to access parameters sent from the javascript calling function, but I also want to acccess controls of the page, like other controls that didnt request the callback, like a gridview control or asp:textbox control, controls that re located on the page but that have nothing to do with the callback call.

Thanks a lot for your help.

PageMethods are static methods and have no access to controls on the page. However the client-side callback can access the DOM.
