Well it seems like this might be a little bit tricky, a quote from the link I gave you:
"While it is not possible to check the file size before upload begins, you can use the client-side OnClientProgressUpdating event to access information about the file size when it first becomes available."
Also check out this documentation article on the known limitations of radupload.
Since this is a security thing with the javascript engine of browsers, perhaps you should consider implementing a progress area/manager. I do believe you could set them to visible = false and still maintain the functionality behind them (the communication that you need between the client and server).
