I need to have a custom validator that can in some way incorporate a custom variable when calling the client-side javascript validation. This validator is used in a repeater, and every item in the repeater needs to use the custom validator, but validating against its own variable. Is this possible and how can I do it? Example, I need its javascript validation function to be like JavascriptValidation(sender, args, MYVARIABLE) Or is there any way to incorporate my variable in the 'args'? I'm not sure what that is.
