I would like to use the FileUpload Control on an Asp.Net form. And I'd like
to save and restore the FileName between sessions. It seems the property is
read only.

Is there a way to browse for a local file from an Asp.Net page and retain
the file name from session to session?

I've not been able to find anything using Google!

Thanks and Cheers,

The FileUpload control does not allow this for security reasons. If it did
allow such things, hackers could set the default filename to any standard
file on your system to queue it for upload to their servers.
