Does anybody know how you write a validator that validates a field based on another field? What I have is a radio button and a text field. The radio button has 3 options let's say A, B and C. Only if the item B is selected, then I want to validate the text field based on some regular expression criteria.
Is there a way for me to write a Custom Validator to do this 'conditional' validation, or do I need to just do manual validation of the form?
