Ajax based username availability check

Question

Anyone have examples for creating a new user registration form where the web application checks for username availability via making an ajax call on the form and returning available or not on the same page without a full page post? Something similar to new user registration on Hotmail.

Answer 1

This seems to be a pretty straight forward tutorial. There really isn't that much to it.

This article I wrote has a sample project. That can get you started: Membership Using ASP.NET AJAX
