For itemcode, I am using dropdownbox which is populated with all code and new code option when user click new code option a newtextbox becomes visible. my problem is how can I make newtextbox mandatory field whenever new option field is selected(as it may left blank in case of edit option
And making requiredfield validator not workable ).

I still use client side validation - less overhead. HTH.
