no, I was just playing with those settings, I need only 1 file to be uploaded, anyway, when upload happens automatic postback occurs, so user will not have a chance remove it. That page is where, let's say, similar to "avatar" upload, you click button, choose picture - it get uploaded and applied instantly and another button appears - Remove image.
I haven't checked yet "fail" scenarios, but now it behaves as I need, except inline progress, I'd like to show existing ProgressArea.
Currently I tweak the view online progress by changing ruUploadProgress, but still, I'd like to switch if "off" and show progress area that I have. Please refer another my post, where I manually start progress manager's polling, it shows statistics of files being uploaded, but polling of the server never stops, even more if I stay at same place and continue uploading files - polling speed increases.
My current working async upload:
Localization-Select="<%$ Resources:PGC, ProjectContentElement_UploadImage %>"
Localization-Cancel="<%$ Resources:PGC, General_Cancel %>"
Localization-Remove="<%$ Resources:PGC, General_Remove %>"
