About RadAsyncUpload for ASP.NET AJAX
Perform configurable asynchronous uploads of single or multiple files using RadAsyncUpload for ASP.NET AJAX. The control addresses the limitation to perform file uploads with plain post backs only, and supports web farm scenarios, as well as internal validation, using its http handler for this purpose. RadAsyncUpload provides smooth file async upload handling with rich progress status information display, and its efficient proprietary http handler allocates minimum server memory.
RadAsyncUpload and 80+ 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.
