expression.OnLostFocus
expression Required. An expression that returns one of the objects in the Applies To list.
Remarks
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 LostFocus event occurs when the object loses the focus.
The OnLostFocus 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 Lost Focus box in the object'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 Lost Focus box is blank, the property value is an empty string.
Example
The following example prints the value of the OnLostFocus property in the Immediate window for the button named "OK" on the "Order Entry" form.
Debug.Print Forms("Order Entry").Controls("OK").OnLostFocus
