How to decide to use ComboBox control instead of a ListBox?
- If you want the user to be able to add items, use a ComboBox.
- If the form has a large number of input fields, and space is at a premium, use a ComboBox.
- If the list being manipulated contains only a few items and those items will not change, use a ListBox.
- If the list contains a very large number of items, and the user will select from the items on one form to load another from, use a ListBox.
