ASP.NET.in.a.Nutshell.Second.Edition [Electronic resources] نسخه متنی

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.
