1. Why cant I access page controls in PageMethod?
PageMethod is invoked via Reflection.
When the server receives a request for the PageMethod, it uses ProcessRequest(HttpContext context) method in System.Web.Script.Services.RestHandler class to serve it. Reflection is used internally to invoke PageMethod which is public and static.
Its not accessed via an instance of the page. Also, this request doesnt go through the regular lifecycle of a normal request for .aspx page. Therefore, controls on the page cant be accessed inside the PageMethod.
