WebForms TreeMap Overview

About RadTreeMap for ASP.NET AJAX

The main advantages of the control are that you could:

  • visualize huge data in a meaningful and colorized way (i.e. the hard drive folders and files structure divided by size; the popularity of different mobile devices on the market, and other)
  • optimize space on your web page by its compact structure

RadTreeMap 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.
