Is there a way to check to see if the value of a combo box or text box has changed? I have placed my code in the AfterUpdate() event of a control but how can I be sure the user actually changed the data? For example the user may click on the combo box and actually choose the same selection that it was originally. In this case I wouldn't want to do anything. Is there an event I can use that is only trigged if the data actually changes?
