ASP.NET in a Nutshell

Name

DropDownList

Synopsis

This class provides a single-selection drop-down list control. Various properties, such as BorderColor, BorderStyle, and BorderWidth, allow you to configure its appearance. To add items programmatically, use the Items collection or use the DataBind() method to bind to a data source (such as a System.Data.DataTable or a System.Array).

Use the SelectedIndex property to determine the selected item or the SelectedItem property, which returns a ListItem object that specifies the associated text.
