Hello,

I set dynamically ValidateOption.AllowedFileExtensions to limit the upload to given file extensions, and it works well in IE. But with Chrome and other browsers the setting simply doesn't work and I'm able to upload any file extension. I tried to change the delimiter of the allowed extensions, testing both the comma and the semicolon. The same: IE ok, the others not. Testet even with only one file extension: nothing changed.

Did I forgot anything?

Thank you four your help,

Daniele
