I have a form with a FileUpload field.

When the form is submitted, the selected file is not saved to the media folder, or anywhere else that I can see. It's as though the submit process is just ignoring the file.

There are no errors in the log.

Is there some special configuration that I need to do to get the FileUpload to work?

I have also tried installing Perplex Form package and using their ImageUpload field but I have the same issue.

EDIT: In FileUpload.ProcessSubmittedValue, context.Request.Files is null, but I don't know why...

HttpFileCollectionBase files = context.Request.Files

EDIT: I'm using WebForms, not MVC - could this be why?
