The error message is very clear. What is the issue?

Check the e.RowIndex value - it is probably negative to indicate no row.

That's probably it :-D
C#
string product = GridView1.DataKeys[e.RowIndex].Value;


The problem might be with the .Values["product"].

Check do you have datakey with the name "product".
