Validator in ASP. netajax

Today, in the project, I found that validator is unavailable in Asp.net Ajax, so I went to Google and found a good solution.

The problem is solved, but the usage of tagmapping is indeed an eye-opener for me. I used to read this element when I was reading msdn. I have never thought about its practical use. It seems that I still need to do more work.

Msdn defines a set of tag types that are remapped to other tag types during compilation.

I have to admit that this explanation is abstract enough, so I met the mattgi application today. In fact, the control defined in tagmapping will replace all the controls of the same type under the configuration file site.
