When do you want to get the information - as the selection is changed or at some other time?

Once you want to use ComboBoxStyle.DropDown, you want to allow your user to edit/type something other than ones already in the drop down list. So there are 2 cases:

1. If user chooses something which is already in the drop down list, then you can access the selected ID via SelectedValue property of your comboBox.

2. Otherwise, it should be a new item, the behavior is depending on you, for example, you may want to show some message box to ask for user to add new item or automatically add the new item (with a new automatically generated ID).
