my validation routine

[Guest]

hey all,
i have a gridview where i need to do some custom validation. i'd like to
extract the validation procedure as much as i can.

so what i'm doing is whenever a user selects save i call the validation
routine and pass it the gridview row object for validation. does this sound
ok to do? is it true that when you pass an object such as a gridview row it
doesn't matter how it's passed via ref or copy it's always going to be via an
implicit ref?

thanks,
