I recently learned about ajax.net Ajax. After searching on the internet, I found the blog terrylee's tech space. After reading Ajax content, I was attracted. I personally think this is a good teaching material for beginners of Ajax.
[Ajax ASP. NET Ajax entry series (1): Overview] describes ASP. NET Ajax components.

1. ASP. NET Ajax: This part is ASP. net Ajax core, including the core Ajax type system, network protocol layer (networking stack), component model, extender (Extender) base class, and ASP.. Net integrated server functions (including popular scriptmanager, updatepanel, and timer controls ).
2. ASP. NET Ajax "value-add" CTP: ASP. NET AjaxCommunitySupported "value-added" CTP, including the additional advanced features included in previous Atlas CTP versions, but not fully supported in "core" 1.0. Through further feedback, these will gradually and steadily increase to core 1.0.
3. ASP. NET Ajax Control Toolkit: Contains 28 cool free Ajax controls based on the "core" download version of ASP. NET Ajax 1.0. It is an open-source project developed by Microsoft and non-Microsoft developers.
