Dynamic RequiredFieldValidator

[staeri]

In my FormView I have a dropdownlist (dd1) and a textbox (txt1).

It's ok to save a record if both are empty or both are filled. If a
value is selected in dd1 then txt1 should also be filled to be saved.

How can I handle this with RequiredFieldValidator?

Very grateful for help!

I would opt for a CustomValidator, as it allows you to write fairly complex
validation code. Either that or get rid of client side validation on this
particular element.
