Magic AJAX is Tragic AJAX – Use AJAX for ASP.NET
We have used magic ajax in our implementation in ASP.NET 2.0 web application. But there are many problems in our web application using Magic Ajax. Main issue is with Validation Controls and the controls updates. Also there are many questions regarding the Validations but maximum queries are unanswered.
We have replaced the Magic Ajax with AJAX for ASP.NET and its working great!!!. So guys, do not use Magic Ajax until they release stable version.
