Hello! I was wondering how to populate the multicombobox from the backend and not by user, from the parent control. Scenario, I am using your code base (Multi Select ComboBox in WPF[^]) for user to save items to database. I now want to allow the user to pull all the items previously selected to re-populate the multicombobox. I have been trying but with no success. Many thanks on any advise you can provide! James
