Customize Error Message caused by uploading big file? (No DNS error)

[henry]

Hi all,

When user upload a file, there is a size limit (default is 4M). And we
can change this size limit by changging the config file.
If a user upload a file bigger than this size, an DNS error will be
displayed.
Now my question is whether we can customize this error message?
Displaying a DNS error page is quite misleading to normal user.
I would rather display a page saying "The file you upload should not
exceed 4M" and then put a link there for the user to go back to
previous page.
Is this possible?

Thank you.

Henry

Yes, it is possible

put the upload inside of a try/catch block

tr

// uploa

catch(Exception ex) // or the more specific DNS Exception you receiv

// if it is a DNS Exceptio
lblErrors.Text = "The file could not be uploaded. Files over 4mb are not allowed. Please check the file size and try again.
}
