Hi everyone,

When I click on "Cancel upload", an alert popup shows up "file error : XXXXXX undefined".

Why ? 

Hi vincentUCF,

Do you get the same problem on http://www.ajaxuploader.com/Demo/Large-File-Upload.aspx? I can not reproduce this issue. 

And you can try catch the error, and handle it by your own logic, and do not show any alert. More details please refer to http://www.ajaxuploader.com/document/scr/html/How-to-catch-uploader-error.htm

I don't have the error on the sample page.

And I tried to catch the error but it doesn't work. 

Hi vincentUCF,

If the demo page works for you, can you try the same code on your own page? Does it work too? Can you show me what code you are using?

Regards,

Ken
