Hi
 
How i can validate that file which i selected for upload, isn't exist in destination folder specified below, before starts uploading?
Maybe there is exists a event OnSelectUploadedFile e that executes on server side?

Dest folder: C:\UploaderTemp

I have a event that checks file exists or no in FileUploaded event.
It will be great, if there is a possibility to do pre-validation.

Thanks,

Alexey
