I'm rather new to ASP .Net, so I appologize in advance if I'm asking a dumb
question here. I've been searching all over the place for an answer and
haven't found a single one.
I'm working on a form that gives the user a file control to upload a file
from their machine to my server. With this file control are two buttons; one
marked "Upload", the other marked "Cancel". The cancel button is to give
them the option of just backing out entirely. Upon clicking the Cancel
button, the C# code redirects them to the previous page.
The problem I'm having is that if the user has already selected a file on
their computer (through clicking Browse, etc.) and they click "Cancel" the
file is uploaded to the server anyway. How do I prevent the upload if they
click the "Cancel" button and not the "Upload" button.
Thanks in advance,
ed
