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 70+ other controls are part of RadControls 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 the business logic of the app.
