Sets or returns the value of the On Click box in the Properties window of one of the objects in the Applies To list. Read/write String.


expression Required. An expression that returns one of the objects in the Applies To list.


This property is helpful for programmatically changing the action Microsoft Office Access 2007 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 Click event occurs when a user presses and releases the left mouse button over an object.

The OnClick 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 Click 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 Click box is blank, the property value is an empty string.


The following example associates the Click event with the "OK_Click" event procedure for the button named "OK" on the "Order Entry" form, if there is currently no association.

With Forms("Order Entry").Controls("OK")
If .OnClick = "" Then
.OnClick = "[Event Procedure]"
End If
End With
