RadUpload has been replaced by RadAsyncUpload, Telerik’s next-generation ASP.NET upload component.
If you are considering Telerik’s Upload control for new development, check out the documentation of RadAsyncUpload or the control’s product page.
If you are already using RadUpload in your projects, you may be interested in reading how easy
the transition to RadAsyncUpload is and how you can benefit from it in this blog post.
The official support for RadUpload will be discontinued in June 2013 (Q2’13), although it will still
be available in the suite. We deeply believe that RadAsyncUpload can better serve your upload needs and
we kindly ask you to transition to it to make sure you take advantage of its support and the new features we constantly add to it.
Since Q2 2010 all new functionalities are listed in the control's Release Notes posted
Added RadAsyncUpload control which allows
asynchronous file uploads and works flawlessly in ajax panels.
