PowerWEB LiveControls for ASP.NET is a suite of 20 AJAX enabled (Asynchronous JavaScript and XML) controls that allow you to build Web applications that don't require a postback. Just like the Microsoft intrinsic controls, LiveControls trigger events in code-behind, but do not require the client browser to be refreshed when data is sent back to the browser. Commonly known as Ajax, or client callback, this technique helps you create richer and cleaner Web applications by eliminating the flicker and delays associated with a postback, providing a smoother Windows-like behavior for the application. No need for Flash, Java Applets, or complex JavaScript, and extensive browser compatibility is automatically provided.
