There are many design considerations to take into account, based on the requirements of a specific project.

However, its server-side processing model has several drawbacks inherent in the technology: Enter Microsoft's ASP. AJAX, which stands for A synchronous J ava Script A nd X ML, is an integrated framework for providing incremental page updates via cross-platform Java Script, composed of server-side code comprising the Microsoft AJAX Framework, and a script component called the Microsoft AJAX Script Library. NET AJAX extensions also provide cross-platform support for accessing ASP. This whitepaper examines the partial page updates functionality of the ASP.

However, there are significant performance considerations to bear in mind, both in terms of behavior and speed.

The ability to integrate partial page rendering is integrated into ASP. When you launch your website, you should see that partial rendering is now enabled, because when you click on the button there will be no flicker, nor will there be any change in the page scroll position (this example does not demonstrate that).

If you were to look at the rendered source of the page after clicking the button, it will confirm that in fact a post-back has not occurred - the original label text is still part of the source markup, and the label has changed through Java Script.

Each Update Panel is isolated, so that each can work independently (you can have two Update Panels running at the same time, rendering different parts of the page, independent of the page's postback).
