Dropdown List Box display type
A dropdown list box is a control that contains a list of objects or options from which the end-user can select one.
Guidelines for the use of dropdown list boxes are:
•Display options in a logical order (e.g. alphabetically or numerically).
•Make the display length big enough to display the longest option.
•For each option, consider setting Value and Prompt to the same string value. This keeps you from constantly having to look up the Value-Prompt mapping during development.
