panelJAX enables you to rapidly build rich async-enabled web-sites. It integrates with ASP.NET MVC and allows you to make business logic decisions server-side, that control your UI client-side. Best of all, there's nothing new to learn. You can continue building your HTML views that same way you always have, and panelJAX seamlessly ajaxifies it!
panelJAX is a jQuery plugin, and .NET assembly containing helpers and attributes for ASP.NET MVC.
