You can now reference fields from other panels by clicking on them when you're
editing a formula. You can also reference buttons and the other items that
make up an app from your formulas by clicking on them.
Fields, buttons, calculation panel groups, text boxes, list panel options and
panels now offer a variety of calculated properties you can use to make your
apps more dynamic. This post offers the complete list.
Use formulas to hide and validate fields, make buttons grayed-out, determine
the recipients of reports and more through calculated properties. These
formulas are evaluated when your app is run and make it possible to build far
more dynamic, complex apps.
Use cross-references to refer to other panels with our next release, enabling
you to build truly large, inter-connected apps. This update also lays the
groundwork for calculated properties, which are coming soon.
Use data validation to flag invalid values with our next release. Specify
allowable intervals for number fields to determine validity. A later release
will allow you to use formulas to determine if a field is valid or not.
Access the formatted values of fields from formulas and prevent persistent
fields from being reset with our upcoming release. Also, apps will look better
on desktops and on tablets and the app creation experience will be improved.
