For each uploaded file, I would like to add one or multiple additional field(s) which would be a file (so the goal is to add either a basic input[type=file] or a Telerik AsyncUpload).
How to achieve this ?
I got to add input[type=file] additional fields but the files are not posted and I can't get the binaries on the server side.
ListFiles(i).GetFieldValue("additionalFileInput") returns a string that is the selected file name.
How could I get the binaries from additional fields that are file inputs ?
