Semantic Rendering for Better Page Responsiveness

Telerik’s TreeView control for ASP.NET AJAX uses advanced CSS rendering with list items rather than HTML tables in order to keep the page output clean and minimal. The semantic rendering not only improves the responsiveness of your applications but also makes your web pages more easy-to-crawl for search spiders and thus, more SEO-friendly.

Powerful Server-side and Client-Side API for Maximum Flexibility

To implement advanced and specific scenarios take advantage of the public methods, properties, and events found within the Tree for ASP.NET AJAX. Almost all user actions raise an event which provides all the arguments you need, both on the client and the server. The multiple public methods and properties give you the freedom to interact with the control and manipulate it not only upon initial load, but also through the whole user session.

Accessibility and Internationalization

Telerik’s ASP.NET Tree control is Section 508 compliant and covers the W3C Web Accessibility Guidelines 2.0. This makes the control accessible to people with disabilities, as well as users of all kind of devices and interfaces: desktop browser, voice browser, mobile phone, etc. Support for right-to-left languages is also available out of the box.
