The DropDownList Web server control enables users to select from a single-selection drop-down list box. The DropDownList control is similar to the ListBox Web server control. It differs in that it shows only the selected item in a box, along with a drop-down button. When users click the button, a list of items is displayed.

The following table lists topics that provide information about how to work with the DropDownList control. Because the control is similar in many ways to the ListBox control, some of the links below lead you to topics for that control.
