section, a hidden field, or perhaps a block of server-generated data to share with the JavaScript environment. Any UpdatePanel record is resolved by extracting the markup and attaching that to the <div> or <span> tag in the DOM with a matching ID. The DOM update occurs through the innerHTML property, as shown here:

Similarly, hidden fields are resolved by loading the new content into the matching DOM elements. Finally, server-generated data (referred to as data items) that needs to be loaded into the JavaScript engine is made available to JavaScript functions and page event handlers. You can use any number of UpdatePanel controls in your page. The only limitation might be the total number of controls you end up having in the page if you add too many updatable panels. Likewise, UpdatePanel controls can be freely nested. Because a partial rendering page doesn t interfere much with the standard page life cycle, any security barrier you might have in your application remains functional. The timing of an asynchronous postback, in fact, is like that of a postback and occurs after all authentication and authorization steps have been taken.

Partial rendering is definitely the easiest way to add AJAX capabilities to an ASP.NET Web site. The impact on existing code is close to zero. It doesn t require significant new skills, doesn t require exposure to JavaScript, and leaves the application model intact. All that you need to learn is how to use a small set of new server controls UpdatePanel, ScriptManager, and UpdateProgress. No new application architecture is required, and no code refactoring needs to be done. Advocates of a pure AJAX approach might say that partial rendering completely misses the whole point of AJAX. And such a statement is not a false one. Overall, partial rendering is only one possible way to approach AJAX. It preserves most of your current investments and is relatively cheap to implement. Partial rendering just makes your pages refresh in a smarter way, thus delivering the same pleasant effect of a canonical AJAX feature. Partial rendering doesn t turn your existing application into a true AJAX application. There s no new architectural point in partial rendering. It s a great technique to quickly update legacy applications, and it s an excellent choice when you lack the time, skills, or budget to move on and redesign the application. But in a good number of cases, an improved user interface and optimized rendering are all that your users demand. So partial rendering would perfectly fit in. And, as if we needed more reasons to use it, partial rendering is actually tremendously effective.

In any case, you should also be aware of the structural limitations of partial rendering. You might want to start with partial rendering to improve your pages and then move on to other, more purely AJAX, solutions to fix particular bottlenecks that still remain. JavaScript will never make you productive; a server-side application model will never give you the responsiveness and interactivity users loudly demand. Finding the right balance and making the correct trade-offs is entirely up to you and your creativity. AJAX is cool, but AJAX is structurally a tough trade-off to make. Let s see the other side of the coin: scripting functionalities directly from within the browser. Note Why is it so darned hard to write pure AJAX applications AJAX applications are all about the client, and the client is JavaScript and HTML. Both JavaScript and HTML have significant limitations in light of the complexity of today s applications.

JavaScript is an interpreted language, and it does not have a particularly modern syntax. Additionally, JavaScript is subject to the implementation that browsers provide. So a feature might be flaky in one browser and super-optimized in another. Originally born as a document format, HTML is used more as an application delivery format. But for this purpose, HTML is simply inadequate because it lacks strong, built-in graphics and layout capabilities. Silverlight with its embedded Common Language Runtime (CLR), support for managed languages and full support for Windows Presentation Foundation (WPF), tries to address both issues.
