Executes when a field loses focus after its value has been
changed.
OnValidate()
Applies To
Pages
Remarks
Use this trigger to validate user entries in a page field. If
validation fails, then the field is marked with an error and its
value is not saved.
The OnValidate trigger is also a field trigger at the table
level. For more information, see OnValidate (Fields)
Trigger. If both the table field and page field triggers
are defined, then the OnValidate trigger on the table field is
executed before the OnValidate trigger on the page field.
Note
You can use this trigger to write to the database. You cannot
call the UPDATE function from this trigger.
