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.
