I have 6 RadUpload controls on my page. The page also has a number of UpdatePanels. The RadUpload controls are NOT contained within an UpdatePanel. Whenever one of the UpdatePanels does a partial page postback, it appears that the RadUpload controls kick-off the upload process. That is, when the parial postback is performed, requests start happing for Telerik.RadUploadProgressHandler.ashx?RadUrid=aea494f2-65ea-43ca-88ce-a02b0e247da2&RadUploadTimeStamp=1228431329855&. I assume that these are RadProgressArea polling the the upload handler.
These request happen quite frequently, and they appear to be a real drag, latency-wise.

Is there a way to prevent this polling from starting untill a specific button is clicked?
