Restrict a custom combo box to listed data only

Simple issue. I have a combo box that I have added to a form. It has a list of data to select. User have the ability to type in whatever data that they want into the field. How to I limit to only the options the drop down has? Thanks!


I see you never got a reply to this. I am interested in doing this for my combo box. I thought there was a property to set someplace that would restrict the value to one only in the list. However I can’t find it now. Did you figure this out?

I found this post that solved it for me. Hope it works for you too!
