When I remove UploadType="IFrame", and I try to upload files, I get a prompt that asks for my user name and password (Unacceptable). However just for testing purposes I enter Admin accounts user name and password... following occurs:
1. I don't get prompted again
2. Next it seems like the first file on the queue is being uploaded (as the in progress circle starts turning next to the file)
3. After a long time, that I realize nothing is happening, I actually realize the entire form including my browser is frozen
So removing UploadType="IFRAME" prevents me from uploading files :-(
I need to clarify, I'm storing my files into my SQL-Database
