Custom validator on multiple fields?

[Tarun Mistry]

Hi everyone, is it possible to make a custom validator work on multiple
fields?

I have 3 input text boxes, I would like a validator that checks to ensure at
least 1 of them contains informaion before allowing the form to be
submitted.

Any help apprecated,

Kind regards
Taz

Hi,

you can use CustomValidator so that don't specify the ControlToValidate at
all. In that case, you'd sort of hard-code in the validation logic which
controls you check for with it. That way you can check multiple of them.

I've also developed (though a long time ago, so the quality of code is what
it is) such validator which can take the controls to be validated as
comma-separated string
