Telerik Delivers Next Generation
ASP.NET UI Components

RadControls for ASP.NET AJAX redefine industry standard

We live in a world of constant motion. Ideas, aided by the Internet revolution, rapidly transform from concept to reality and drive the wheels of progress forward. Stand still for too long and you’re outdated, dull, and losing to a new competitor that is riding the “2.0” wave. Nowhere is this reality clearer than in web development, where the oft hyped “Web 2.0” has become the mythical measuring stick by which all websites are deemed hot or not. If your website isn’t deemed “Web 2.0,” it’s already considered old fashioned.

Catching the “Web 2.0” wave, though, isn’t always easy. Most UI components claim they can help you find your “Web 2.0” Zen, but few actually deliver on those promises. They entice you with “Ajax-enabled controls” and components that do everything under the sun, but as you begin to examine the controls you find they force you to use “heavy” Ajax callbacks and proprietary- often inconsistent- APIs.

How can you build “Web 2.0” sites with
“Web 1.0” UI components? You can’t.

To build truly next generation websites, you need UI components that give you the power and flexibility to harness the speed of Ajax and rich experience of client-side programming- all without requiring you to write any JavaScript. Telerik is delivering the UI component suite that meets all of these requirements with its next generation RadControls for ASP.NET AJAX.

Built for the future of ASP.NET
Over a year ago, Microsoft released the “official” Ajax framework for ASP.NET with the ASP.NET AJAX Extensions for ASP.NET. The new cross-browser Ajax and client-side programming library finally provides ASP.NET developers with a Microsoft designed and supported framework that they can depend on to implement projects of all sizes.

Telerik recognized early in ASP.NET AJAX’s development that it represented the future of ASP.NET development. Not only does the new framework standardize the API for Ajax programming in .NET, it also provides a radically simplified way to write client-side code. By integrating the ASP.NET AJAX core in to UI components, Telerik realized that it could deliver client features and performance previously very difficult to achieve.

Telerik’s new RadControls for ASP.NET AJAX, formerly RadControls for ASP.NET “Prometheus”, is the culmination of over a year’s worth of work to build the most comprehensive ASP.NET UI suite directly on Microsoft’s ASP.NET AJAX. The suite delivers incredible performance gains over previous Telerik UI suites for ASP.NET and it adds many new controls to developers’ ASP.NET toolboxes.

Among the new controls and features in the RadControls for ASP.NET AJAX are:

RadScheduler: By combining the proven usability of Outlook® with the innovative input mechanisms of Google Calendars in a flexible and easy to configure component, RadScheduler makes it easy to add a rich scheduling UI to any ASP.NET application.

RadAjax for ASP.NET AJAX: Building on the simplicity of Telerik’s RadAjax for “classic” ASP.NET, RadAjax for ASP.NET AJAX gives you the tools you need to quickly and effortlessly add ASP.NET AJAX to your website. Stop wasting time with UpdatePanels and Triggers and let RadAjax do all of the ASP.NET AJAX configuration for you.

Rendering on the client: Many of the components in the RadControls for ASP.NET AJAX suite are now capable of rendering on the client. That means the controls can use JavaScript to render their UI in the browser, reducing trips to the server and speeding-up your application’s performance.

Ajax on a diet
Most UI components that provide out of the box Ajax support, including Telerik’s “classic” ASP.NET UI components, do not enable you to realize the maximum performance Ajax can provide. That’s because most ASP.NET Ajax frameworks, even ASP.NET AJAX by default, execute the full ASP.NET page lifecycle with every asynchronous Ajax callback. While that makes the transition from PostBack to Ajax programming easy, it also negatively impacts the efficiency of Ajax callbacks because “heavy” data fields like ViewState travel back and forth with every async request.

To truly get the most of out of Ajax, you need to execute asynchronous calls that are devoid of ViewState data and that don’t labor through the entire ASP.NET page lifecycle. The solution is Ajax calls to web services. Even though the solution is obvious, it is often avoided because it normally requires a lot of tricky JavaScript programming to initiate the web service call, parse the returned JSON data, and then update the page.

High-speed Ajax is easy with the
RadControls for ASP.NET AJAX

Telerik’s new RadControls for ASP.NET AJAX make the process of using “high-speed Ajax” as easy as setting a couple of properties. By telling controls like RadMenu and RadTreeview where your web service is located and the name of the method to call, the controls will automatically bind to your web service and begin delivering incredibly high performance Ajax operations. No JavaScript required. No ViewState sent back and forth. Just efficient, compact, optimized Ajax updates.

Performance. Performance. Performance.
All of the features in the world can’t make-up for ASP.NET UI components that perform slowly. In fact, components that deliver “all of the features in the world” are usually the worst performers. Telerik has changed that equation with the RadControls for ASP.NET AJAX by leveraging innovative new load-as-needed script resource handlers and optimizing client-side and server-side code. Telerik’s RadControls for ASP.NET AJAX deliver some of the highest performing controls for ASP.NET without sacrificing the features you need to be productive.

For example, the new RadEditor for ASP.NET AJAX loads up to 4 times faster than the previous non-ASP.NET AJAX versions. That means you can deliver the industry leading WYSIWYG browser-based editor without taking a hit in your page’s performance metrics. Meanwhile, RadGrid will soon receive a brand new data binding engine in ASP.NET AJAX that effortlessly handles sorting, filtering, and paging hundreds of thousands of records in mere milliseconds. In side-by-side performance comparisons to other leading ASP.NET grids, Telerik’s new RadGrid for ASP.NET AJAX performs at the top.

Finally, new utility controls like RadScriptManager and RadStyleSheetManager maximize your page optimization by combining all RadControl script files and stylesheets in to single link references on your page.

Keep it clean
One area where Telerik continues to lead the industry with its RadControls for ASP.NET AJAX is clean, semantic HTML rendering. This has long been a staple of Telerik’s ASP.NET controls and the dedication to light weight, standards compliant HTML rendering continues with the new controls. Many UI components for ASP.NET make excessive use of tables and inline styles when they render, producing bulky HTML that slows down your page. Telerik’s controls, on the other hand, use the least amount of HTML possible when rendered and rely on modern, cacheable CSS style sheets to provide control styling.

Don’t Compromise
If you’re tired of working with UI component suites for ASP.NET that get in your way, perform slowly, and don’t provide you with all of the tools you need for your applications, a clear solution to your problems has arrived. With the RadControls for ASP.NET AJAX, you can create high performance ASP.NET applications with rich user interfaces that pass today’s “Web 2.0” standards. From rich scheduling components to simple color pickers to innovative Ajax management components, Telerik’s RadControls for ASP.NET AJAX has everything you need to make your next project a success.
