问题 I've created a particular server control that has some methods I'd like to call from javascript. I know that the ScriptManager allows to call a web service or a page method.

问题 Q1: Is there something like too much ajax?? Explanation: I have been seeing programmers using Ajax/jQuery etc where I think its not even required. I had built a reporting tool for the company's senior management ( age group 55+) and had to refactor many pages and actually take out the ajaxy stuff from it.

Other good plug-ins exists as well as other good javascript libraries, but MS is getting behind jQuery and jQuery UI is the official UI library. http://jqueryui.com
