Hi @Perc,

Thanks for the reply. It has enhanced my vision towards error handling but my issue is not fixed.

If I try to be specific then the issue is that I want to change the warning/error messages for File/Image attachment control as the attached image shows in my first post. 

"File not uploaded. Details" should be in another language and same for "The file is larger than the maximum size."

Regards,

Asad Naeem
