Selecting Multiple Files
With MultipleFilesUpload="true" the file dialog accepts a multi-file
selection, and FileUploaded is raised once per file.
This is the scenario most upgraded v4 pages use, and the one to check first if
server events are not firing: v4 always posted back when the batch finished, and
the legacy controls restore that by forcing AutoPostBack on.
