GXT Form Validation

[bboyle18]

Hi,

Just wondering if there are any plans to build in form validation to GXT?

Thanks

Brian,

FormPanel does have an isValid method that checks validation of all contained fields - with that you can have standard and custom validation for all fields.

cheers,

Hi..

If I want to make an email validation in a textfield, how can I do that?
In GWT-Ext we can use :

TextField email = new TextField("Email", "email");
email.setVtype(VType.EMAIL);

How to do that in GXT? Is there any tutorial?
Thx for any replies..

Regards,
Retha

TextField<String> emailaddress = new TextField();
emailaddress.setValidator(validator);

    private Validator validator = new Validator() {

        @Override
        public String validate(Field<?> field, String value) {
            if (field == emailaddress) {
                if (!emailaddress.getValue().toLowerCase().matches("(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|\"(?:[\\x01-\\x08\\x0b\\x0c\\x0e-\\x1f\\x21\\x23-\\x5b\\x5d-\\x7f]|\\\\[\\x01-\\x09\\x0b\\x0c\\x0e-\\x7f])*\")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\\x01-\\x08\\x0b\\x0c\\x0e-\\x1f\\x21-\\x5a\\x53-\\x7f]|\\\\[\\x01-\\x09\\x0b\\x0c\\x0e-\\x7f])+)\\])")) {
                    return "Bad E-mail Address";
                }
            }

            return null;
        }

    };

Thx TheBuzzer...

I also find the answer :

TextField<String> email = new TextField();
email.setRegex(".+@.+\\.[a-z]+");
email.getMessages().setRegexText("Bad email address!!");
email.setAutoValidate(true);
