    qxdotnet

    qxdotnet is a server side ASP.NET wrapper for qooxdoo library

    http://qooxdoo.org is a great JavaScript framework. It contains lots of UI controls that would be useful when developing ASP.NET applications. But qooxdoo designed to communicate with server via RPC method. It is not comfortably. The main qxdotnet idea is a creating C# mirror objects for qooxdoo UI controls. State of the objects on the server and the client is synchronized with AJAX. For example, you just create a C# "button" control and place it on the form. After you start your ASP.NET application, you can see the button inside browser.
