Complete Set of Features and Controls
Enjoy components for every need: navigation and layout, data management and visualization, editing, interactivity and more. In our 11 years of aggressive product development including 3 major and up to 6 minor releases per year we have implemented, tested and optimized over 4,000 features in Telerik ASP.NET controls.

Mobile Support and Responsiveness
No need to build a mobile version of your project since the web sites and apps built with Telerik ASP.NET controls work equally well on desktop and mobile devices.

Use the Page Layout Framework to build responsive ASP.NET applications
Leverage the adaptive, fluid, elastic and responsive capabilities featured in most controls to offer user experiences tailored to each end-user's device
Gain productivity since touch events are handled in the same manner as those triggered by a keyboard or a mouse
Get a better user experience with the two mobile skins especially designed for touch devices that come included in the suite

20 Built-In Professional Grade Skins
Give your applications a sleek, professional look by setting a single property. By applying one of the 20 professionally-designed skins that come with Telerik UI for ASP.NET AJAX, including two engineered with mobile devices in mind, you save design and front-end development time. No need to be a CSS wizard to create or customize the Telerik skins with our web-based Visual Style Builder.

Exceptional Performance and User Experience

We constantly optimize the performance of UI for ASP.NET AJAX to meet your end users expectations. This is why the controls:

Produce minimal and clean HTML and CSS
Minimize j@vascript by loading only whats needed
Reduce postbacks for a better user experience
Compress data transferred between browser and server (Pages, j@vascript, ViewState, JSON data, etc.)
Use built-in CDN support and CSS sprites to deliver content faster to end-users (Telerik covers all CDN costs for you)
Minimize memory usage and have robust code, free from memory leak
