|Access Developer Reference|
expression A variable that represents a Form object.
This property is helpful for programmatically changing the action Microsoft Access takes when an event is triggered. For example, between event calls you may want to change an expression's parameters, or switch from an event procedure to an expression or macro, depending on the circumstances under which the event was triggered.
The Delete event occurs when the user performs some action, such as pressing the DELETE key to delete a record, but before the record is actually deleted.
The OnDelete value will be one of the following, depending on the selection chosen in the Choose Builder window (accessed by clicking the Build button next to the On Delete box in the form's Properties window):
- If Expression Builder is chosen, the value will be "=expression", where expression is the expression from the Expression Builder window.
- If Macro Builder is chosen, the value is the name of the macro.
- If Code Builder is chosen, the value will be "[Event Procedure]".
If the On Delete box is blank, the property value is an empty string.
The following example associates the Delete event with the "Form_Delete" event for the "Order Entry" form.
