Form events offer you the power to control all aspects of the user interface including control over navigation, implementation of data integrity and validation procedures through visual basic event programming. Afterupdate event is triggered and the entire record is updated and the data is saved in the database when:
The control loses the focus
The user presses ENTER or TAB
The focus leaves the record
The user clicks Save Record on the Records menu
Access Event Tutorial – AfterUpdate VBA:
In this AfterUpdate event example we requery a grand total field on the master form after records are updated in the detail form:
Private Sub Form_AfterUpdate()
Note: When validating form field values it is important to know that the OldValue property isn’t set to the updated value until after the event for the form occurs.
If you decide to cancel the update the value of the OldValue property replaces the changed value in the control.
New with Microsoft Access 2010 are table level event procedures. These events are defined in design view or datasheet view of the table. You can create a macro run run code now for the After Update table event. This new capability significantly extends the power and flexibility of Access 2010.
