The On Load rules are checked when you open a form or a questionnaire. Rules are client-side scripts that are executed when a user of the mobile app interacts with the app. Rules are no-code business logic, which are managed using the rules editor, usually in Woodford.

On Load rules are available for the following user interface components:

Use On Load for initialization

On Load rules are the best option when it comes to handling initializations. They are designed and should be used for various steps handling actions connected to the initialization of components or form styles. The reason for this is simple – users must wait for the On Load rule to be fully executed before they are able to see the form in the desired format. By setting up only the initialization actions in the On Load rule, its execution time is minimal (unless you are handling a great number of conditions and steps in the rule).

These are the recommended steps in On Load rules:

Hide/show fields
Enable/disable fields
Hide/show form tabs
Assign styles to fields or to the entire form
Automatically assign values to fields, e.g. date & time, location, company number, etc.

Do not set up hide/show/enable/disable fields and tabs dynamically. The actions related to changes on a form while working with it are better set up in the On Change rule.

Forms

You can use these rules for example to apply a custom format to certain records.

Rule execution

When when you open a form.

Example: Hide email field

If the field Don’t Allow Emails is set to true, make Email field not visible on the form.

Questionnaires

Editing rules allow you to further customize the questionnaire form’s design and usage (hide or disable form fields, assign values to them, etc.).

Rule execution

When when you open a questionnaire.
When a repeatable group is repeated.

Example: Automatically filled fields

You might want that some fields are automatically filled in when a user starts the questionnaire.
