PageMethods还是通用处理程序？

Question

I am making a site where users can reply to topics, open topics, etc. and when the user sends a message, I don't want to postback; it's ugly.

I'm using generic handlers right now but I am having some problems with it. Like updating GridView using UpdatePanel when XMLHttpRequest's onreadystate is changing.

I decided to use PageMethods but I also wanted to ask you.

Which is better, faster and more useful: PageMethods or Generic Handlers?

Answer 1

If you mean with generic handlers web service endpoints then you can make the following distinction:

• You can use PageMethods if the functionality only needs to be available on that page only
• You can use web service endpoints if you want to reuse the functionality.

Personally I practically always use web service endpoints (in my case ajax enabled WCF).
