Examples
The following code example demonstrates how to select items in a ListBox control. If the item is found in the text box, the item is selected and a message is displayed stating the name of the selected item. If the item is not found, no item is selected and a message is displayed stating that the item was not found.
Important
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.

Remarks
An instance of the ListControl abstract class cannot be created directly. Instead, this class is inherited by other classes, such as the CheckBoxList, DropDownList, ListBox, and RadioButtonList classes, to provide common basic functionality.
The properties of the ListControl class allow you to specify the source of the data to populate the list control. Use the DataSource property to specify the data source to bind to the list control. If the data source contains more than one table, use the DataMember property to specify the table to use. You can bind different fields in the data source to the ListItem.Text and ListItem.Value properties of the items in the list control by setting the DataTextField and DataValueField properties, respectively. The text displayed for each item in the list control can by formatted by setting the DataTextFormatString property.
All items displayed in the list control are stored in the Items collection. You can programmatically specify or determine the index of a selected item in the list control by using the SelectedIndex property. The properties of the selected item can be accessed by using the SelectedItem property.
The ListControl class provides the SelectedIndexChanged event, which is raised when the selection in the list control changes between posts to the server. This allows you to provide a custom handler for this event. For more information about how to handle events, see Handling and Raising Events.
The ListControl class implements the IEditableTextControl interface so that derived list-type controls can be used in the template mode of other controls.
