In a case of drop-down combo (Style=0) the text portion entry (not found in the lost portion) is keeping in Combo.DisplayValue property, so you may use in combo.lostfocus event:
IF NOT This.DisplayValue==This.Value && it's the case
*** do something here, e.g. REPLACE myfield With This.Displayvalue, or store it in some property/variable etc.
