The After record action event occurs directly after the current record has been changed.

## Gocha kuusaa dura

## jijjiirraa kuusaa dura

The Before record change event occurs before the current record pointer - SQL cursor - is changed. Return True when moving is allowed, otherwise False.

## ulaagaalee guuti

The Fill parameters event occurs when the form to be loaded has parameters that must be filled out. For example, the data source of the form can be the following SQL command:

SELECT * FROM address WHERE name=:name

Here :name is a parameter that must be filled out when loading. The parameter is automatically filled out from the parent form if possible. If the parameter cannot be filled out, this event is called and a linked macro can fill out the parameter. Return True when the execution of the parametrized statement should continue, False otherwise.

## Vetoable events

Macros can interrupt event execution when they return a boolean value: True allows the execution of the event to continue and False stops the event execution.

The following events are interruptable by returning False:

- Before record action

- Before record change

- Before submitting

- Before update

- Fill parameters
