say suppose i have form with two fields. for validation to fields we can use validation
control but i hard that validation control work properly only with IE browser but user
may have different browser like netscape,hotjava,neoplanet,opera etc then my validation
control may be failed to validate form's fileds. so if this happen, at that time i will
write my programm in such a way as a result if client side validation failed then only
my serverside alidation logic will work other wise not. so tell me the concept how could
i do it.
