NasaVisaMicrosoftFOXSamsungIBMWorld Bank Group

We moved to Telerik ASP.NET AJAX controls from another control suite, and were immediately pleased with the ease of implementation. The RadGrid control is so simple to use, requiring just a few lines of code as compared with other vendors. Support for language localization was a must for us as well, and Telerik provided that. Support has been excellent, and I love the prevalence of articles that can be found online for self-support. The Telerik Demo website makes learning advanced implementation concepts very easy. By wrapping each Telerik control with our own preferences, we were able to quickly standardize usage across the enterprise. The flexibility is great, and adaptation for new developers has been very quick. Thanks Telerik for a great product!

Tony Pirkle
Chief Technology Officer, MediTract, Inc.

I've discovered the BEST quality of Telerik! You can always count on them. I've NEVER before found a support team like theirs. They resolve problems as if they were a colleague of yours!

Davide Giavazzoli

I'm working with the UI for ASP.NET AJAX for the past three years. These controls saved my team countless hours, enabling us to focus on the business requirements and much less on the user interface. The AJAX enabled controls are fast and easy-to-use.

Ami Solomon

Telerik UI for ASP.NET AJAX is incredible. The design is perfect. From the very first e-mail, the service is fantastic. Huge selection of templates, and a creative selection of functional features. The suite is the best of its kind!

Telerik UI for ASP.NET AJAX makes it really easy to create grids and charts with just a few clicks. The results are quick, clean and beautiful. This is exactly what a Web Developer asks for: performance, simplicity, and clean code.

I have been using your controls now for the last 2 years. The support has been exceptional. The controls are easy to use and I highly recommend them.

Wikus Hattingh
Director, EMWIN Systems (Pty) Ltd

The time spent building web pages for my web project was cut by 50% using Telerik UI for ASP.NET AJAX. The return on investment was way higher than the cost of the ASP.NET suite itself. I've been in the IT business for more than 17 years, and Telerik offers the best customer support.
