Set file extensions for FileUpload

[David Thielen]

Hi;

Is there a way to set the extensions in the "Files of Type" for the FileOpen
dialog for the FileUpload control?

Hi Dave,

Thank you for posting.

As for the web page's file upload html element, it doesn't support such
file extension filter as the windows form file select dialog. So far for
file extension checking, we may need to use client-script to manually
validate the file path through the input file element's onchange client
side event.

ok - thanks. I didn't want it for validation, just so only the relevant files
were displayed in the FileOpen dialog.

Thanks for the followup.

Then, we could only use the current behavior so far.
