ComboBox.OnNotInList Property (Access)
Sets or returns the value of the On Not in List box in the Properties window of a combo box. Read/write String.
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 NotInList event occurs when the user enters a value in the text box portion of a combo box that isn't in the combo box list.
The OnNotInList 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 Not in List box in the combo box'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 Not in List box is blank, the property value is an empty string.
