DescriptionA combo box combines the features of a text box and a list box. Use a combo box to give theuser the choice of either typing in the text box ( upper part) or selecting an item from the list(lower part) of the control. A combo box is preferable when you want to give the user a list ofsuggested options (but the user is free to enter own choice as well as list chioces). A list boxshould be used when you want to limit the users to a specific set of options. A combo box isotherwise identical (in terms of methods and properties) to a list box.
