Triggers
This topic provides an overview of commonly used triggers, grouped into the following functional
categories:
block-processing triggers
interface event triggers
master-detail triggers
message-handling triggers
navigational triggers
query-time triggers
transactional triggers
validation triggers
This topic does not list all of the triggers available in Form Builder, many of which have highly
specialized uses. For a complete list of triggers, or for detailed information on a specific trigger, refer to
the Triggers Category Page.
Block processing triggers
Block processing triggers fire in response to events related to record management in a block.
Trigger Typical Usage
When-Create-Record Perform an action whenever Form Builder attempts
to create a new record in a block. For example, to
set complex, calculated, or data-driven default
values that must be specified at runtime, rather than
design time.
When-Clear-Block Perform an action whenever Form Builder flushes
the current block; that is, removes all records from
the block.
When-Database-Record Perform an action whenever Form Builder changes a
record’s status to Insert or Update, thus indicating
that the record should be processed by the next
COMMIT_FORM operation
When-Remove-Record Perform an action whenever a record is cleared or
deleted. For example, to adjust a running total that
is being calculated for all of the records displayed in
a block.
