About RadEditor for ASP.NET AJAX

RadEditor is not simply an HTML Editor. It is what Microsoft chose to use in MSDN, CodePlex, TechNet, MCMS and even as an alternative to the default editor in SharePoint . Whether you need a mere Textbox with Google-like spellchecker, or a Word-like content authoring environment, the result is the same: clean XHTML output, fast rendering, widest cross-browser support, and tons of features. What is more, important enhancements make it the first accessible rich text web editor on the market, offering accessibility support for its sight-impaired users.

RadEditor and 120+ other controls are part of UI for ASP.NET AJAX, a comprehensive toolset taking care of the common functionality of your application, while leaving you with more time to work on its business logic.
