|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 Filter event occurs when a form is opened and its records are displayed.
The OnFilter 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 Filter 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 Filter box is blank, the property value is an empty string.
The following example associates the Filter property for the "Order Entry" form to the event "Form_Filter".
