Hi,
Thanks for posting in the forum. As to your questions:
1) Unfortunately the built-in uploader does not support multi-file upload. You can upload multiple times, but only one file for each upload.
Our standalone uploader does support multi-file upload at the same time. However the browse file dialog still only allows you to pick one file a time (you would browse multiple times). Allowing multi-select with the browse dialog is not possible without using plug-in based technologies such as Flash and ActiveX. Since our uploader is a pure JavaScript + DHTML solution, it does not support multi-select.
2) You will need to handle this event:
