Hello,
The Process() method in custom async handlers is great. However, it is called only upon completed download of a file.
Is there a way to hook into an earlier handler event at the moment the download is initiated? The idea is that I would like to check whether the file is valid as early as possible. It looks bad to have the user wait for a 50MB upload only to tell at the end that the file cannot be uploaded (e.g. if it already exists).
Thank you,
Stephan

Hi Stephan,

You can validate the file on the client side by declaring the desired "MaxFileSize" and "AllowedFileExtensions" as in the demo.
Hope this will help.
