Attachment.AfterUpdate Event (Access)
Returns or sets which macro, event procedure, or user-defined function runs when the AfterUpdate event occurs. Read/write String.
The AfterUpdate event applies only to controls on a form, not controls on a report.
To run a macro or event procedure when this event occurs, set the AfterUpdate property to the name of the macro or to [Event Procedure].
The AfterUpdate event is triggered when a control or record is updated. Within a record, changed data in each control is updated when the control loses the focus or when the user presses ENTER or TAB.
AfterUpdate macros and event procedures run only if you change the data in a control. This event does not occur when a value changes in a calculated control. AfterUpdate macros and event procedures for a form run only if you change the data in one or more controls in the record.
