I would like to be able to check for a file of the same name existing on the server 'before' i postback.

Is there an event i can access right after the file has been uploaded to the temp directory?

 

Thanks,

Dana

Hi Dana,

You can make the check inside a custom handler as explained here:

Another option would be on file select to make a custom request to the server and if the file exists, to cancel the upload.

You can leverage the Manual Upload functionality as well and upon selecting, play the upload only if the files are valid:
