It’s weird that RadAsyncUpload, Telerik’s next-generation ASP.NET upload control, was introduced more than 2 years ago and while its functionality is times richer than the one of RadUpload, the latter is still one of our most widely used controls and the former simply stays in the shadow. People continue recommending our older Upload control in community forums, our customers continue to use it in new projects and we just don’t get it.

Recently there have been quite a few questions popping up around our ASP.NET MVC upload component, specifically when working with it in synchronous mode. Although this variation of uploading files is not really too complex when compared to its asynchronous counter-part, I believe some of the confusion stems from the MVC syntax that is used in our online demo. My goal with this blog post is to provide a bit more clarity to what exactly is happening in this demo, mostly taking a look at the MVC syntax.
