Name
ListControl
Synopsis
This abstract base class for all list controls includes data-binding
functionality (such as DataTextFormatString
, which
specifies the formatting of bound text), an Items
collection, and
properties for returning the first selected item
(SelectedIndex
and SelectedItem
).
Note that items in the ListControl
class
do not correspond to the specific derived control type. For example, a CheckBoxList
control returns its
selected item as a ListItem
, as all list
controls do, not as an individual checkbox control.
