I want to do this as the entire list is several hundred entries. Does anyone have a code example of how to implement this such that changing one combo changes the lists in the other two? Or is there another control alternative that would be easier to deal with? -- Rob Top Paul Lefebvre Post subject: Re: Cascading ComboboxesPosted: Tue Mar 12, 2013 3:25 pm Site Admin Joined: Fri Sep 30, 2005 9:35 am Posts: 916 Location: South Portland, Maine A PopupMenu might be better since the user can type anything in the ComboBox field. But in general, you would use the Change event to know when a selection was made and then use the selection value to reload the next one. I would probably subclass PopupMenu and add a Load method that you can override to populate them. Then you could write code like this: In PopupMenu1.Change event handler: PopupMenu2.Load(Me.Text) PopupMenu2.Change could be similar: PopupMenu3.Load(Me.Text) _________________ Paul Lefebvre Developer Evangelist Real Software, Inc.
