As I mentioned in my previous reply each RadProgressArea on the page monitors the progressing of
the whole page. If there is at least one selected file for uploading in any of the upload controls all progress areas will appear and will measure the progress of the selected files. If there is no selected files in any of the upload controls on the page no one of the progress areas will appear.
If you want to make appear only the progress areas of the upload controls in which there are selected files you should write custom code. However, in this case the progress areas which will appear will measure the progress not only of the files selected in the corresponding upload control, but of the whole page.
All the best,
