Hi Oscar.

>> On its Valid event I send its Value property to a method as parameter. However, the value sent as the parameter (This.Value) from the valid event is not exactly the one to which its bound column is linked to. In other words, the Value property still doesn’t have the required value while the valid is in execution. <<

Hmmmm. This behavior is not typical. If you check the value of the combo in its Valid, it should be the currently selected item in the list. FWIW, this is how I typically check to see if the user has added an item not in the list (in the combo's valid):

IF This.ListIndex = 0 AND !Empty(This.DisplayValue)

It works fine for me. Something else is going on here. Can we see the code?
