validation without a page refresh?

Can someone point me in the right direction on how to create a web form
where I can perform validation without having to refresh the entire page?

For example, I think google uses it, where you can check for the
availability of an email address and the result is contained in that little
area.

How is that accomplished in asp.net?

Any push in the right direction is appreciated.

thanks

If the validation can be completely accomplished client-side, you can do it
all in JavaScript.

Otherwise, you basically have two choices:

1) do a postback and validate the data server-side

2) use AJAX
