The official support for RadUpload has been discontinued in June 2013 (Q2’13) in favor of RadAsyncUpload, Telerik’s next-generation ASP.NET upload control. If you are considering Telerik’s Upload control for new development, check out the RadAsyncUpload documentation or its 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.

Although RadUpload is still 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.
