Field-validation event

Previous Next

A field-validation event is for a column in an application table.

During user interaction, a field-validation event occurs whenever:

The user leaves a field based on the column after entering or changing the column value in it, for example, by navigating to a different field in the same or a different record, or  by attempting to close the window or page.

The user performs an action implying commit, such as choosing File, Save from the menu.

During constraint evaluation, a field-validation event occurs whenever:

A constraint effectively supplies a new or changed value for the column as part of an INSERT or UPDATE manipulation.

Field-validation events activate domain constraints.
