Combination-box controls enable the user to enter data by typing in the entry field or by choosing from a list in the list box. A combination-box control automatically manages the interaction between the entry field and the list box. For example, when the user chooses an item in the list box, the combination-box control displays the text for that item in the entry field. Then, the user can edit the text without affecting the item in the list box. When the user types a letter in the entry field, the combination-box control scrolls the list box contents so that items beginning with that letter become visible.
