I need some help with a prob.
I am validating a text box which ID is "year"(using a rangevalidator which ID is "rv1"). "rv1" only validates when "year" is blank or when max and min values doesn't match with my requirements. What I want to do is validate if the user enters some also invalid information such as string instead of integer values. I don't know where and when to do this?
Thank you in advance and hope you understand my problem.
