    Form validation questions for some of the fields

    Asked by rocky_tar on February 21, 2014 at 12:06 AM

    There are some of the validations that are already there in Form tools like a Text Box for example has validation such as Numeric/Email/Alphanumeric etc.

    I have used lot of Quick tools in my form like Address which does not have any validation. How can I validate , say a zip code in an Address Form tool? or a phone number , that it can only have 10 digits?

    Unfortunately you cannot add validations on the grouped fields like the full address field. If you'd like to have validations in each of them, you have to use normal textboxes.

    For the phone number field, use the input mask feature to limit inputs with maximum digits. Actually, input mask feature is available on textboxes as well.
