Every MVC and Web Forms developer knows that performing a post-back is a time-consuming process. Instead of posting back just to refresh one control like a drop-down list on a page, you can use jQuery and Ajax instead. A typical example is loading one drop-down after selecting a value in another drop-down. In this seminar you learn to create a controller method in MVC that can be called from jQuery to return JSON data. You then learn various methods to process that data to render various list controls on your page.
