This article shows how to easily reload table content in ASP.NET MVC using the jQuery DataTables plug-in. Minimal code is required on the client-side, and on the server-side, we need standard processing functions. This plug-in allows you to create an effective, AJAXified, Web 2.0 interface with minimal effort and straightforward implementation guidelines.
