I have a few questions on the customization of the appearance of the control:
1) How to hide the filename of the file that has just been uploaded? ShowProgressInfo = false does not remove the final text.
2) When using the ProgressCtrlID as a panel (as in your example), the progressbar is still displayed incorrectly. See the behavior below (ignore the message box, that problem is fixed, but as you can see, the progress bar at the top gets visible, but the real progress bar is displayed below):
3) Is it possible to hide the upload / select file button during an upload or do I have to implement this myself?
Thanks in advance!
