Hi Cemal.

>>Which event is run when the user types a value that is not an item from the combobox recordsource.
Thanks <<

There are a lot of events that fire:

KeyPress
InteractiveChange

If you are trying to determine whether or not the user typed in a value not in the combo's RowSource, the best place to check is in the combo's valid with code like this:

IF This.ListIndex = 0 AND !EMPTY( This.DisplayValue )
   *** The user typed in an item not in the list
   *** Take action here to add the item to the RowSource
   This.Requery()
ENDIF
