Validate the city field on form

(0) ShareShare

Posted on by Community Member

I have one ListPage form that has field CIty (EDT is LogisticsAddressCity). Now I have to validate that field, so when putting new record that field has to be only city not some random text with no sence.

How can I do that?

Thanks.

    Hi Dejana,

    You haven't told us if you are using a custom or a standard form. Standard AX uses the logic which can be setup on the Address setup form. You can define cities per country and also enable City validation on the parameters tab page.

    If it is a customization, try to use the same logic.

    For validations you can use modifiedField of table. But how will you validate if the entered value is valid city name. Or if you have city names stored in some table you can use lookup using table relations.

    No, modifiedField() isn't the right place. The corresponding validation method is called validateField(). modifiedField() is called later, when the change was already validated and accepted.

    Nevertheless using the standard features for maintaining database consistency sounds like a better than writing custom code, unless there are some additional requirements.

    My colleague told my that this might be some property on the field on the table. Because when i create new record new form is opened, there I have the field city and I can save whatever I want but Im supposed to not do that, it should save only existing city because the EDT of the field is LogisticsAddressCity.

    Hi Dejana,

    Have a look at the LogisticsPostalAddress table. It has to fields for managing the cities. One where you can specify text you like, the other one to check if it is a valid city based on the address setup settings.

    Verify how it has been done in standard and apply similar logic.

    Thanks, I changed the EDT to LogisticsAddressCityName and made a relation.
