| System.Web.UI.WebControls (system.web.dll) | class |
This class represents a list box control. Use the
Rows property to set how many rows you want to be
displayed in the control at once (and hence, how much space the list
box will occupy). You can also set the
SelectionMode property to
ListSelectionMode.Multiple if you want a user to
be able to select more than one item from the list box at once.
Most of the list-specific functionality, such as determining the
selected item and reacting to a
SelectedIndexChanged event, is provided by the
ListControl class, which
ListBox inherits from.
