Remarks
In this topic:
Introduction
Use the ListBox control to create a list control that allows single or multiple item selection. Use the Rows property to specify the height of the control. To enable multiple item selection, set the SelectionMode property to ListSelectionMode.Multiple.
To specify the items that you want to appear in the ListBox control, place a ListItem element for each entry between the opening and closing tags of the ListBox control.
Use the Items collection to examine the ListItem objects contained in the ListBox control. For example, you can determine the selected item(s) in the ListBox control by enumerating the Items collection and testing the Selected value for each ListItem element.
The ListBox control also supports data binding. To bind the control to a data source, first create a data source, such as one of the DataSourceControl objects, that contains the items to display in the control. Next, use the DataBind method to bind the data source to the ListBox control. Use the DataTextField and DataValueField properties to specify which field in the data source to bind to the Text and Value properties, respectively, of each list item in the control. The ListBox control will now display the information from the data source.
Caution
This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. You can use validation controls to verify user input before displaying the input text in a control. ASP.NET provides an input request validation feature to block script and HTML in user input. For more information, see Securing Standard Controls, How to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Validating User Input in ASP.NET Web Pages.
Accessibility
For information about how to configure this control so that it generates markup that conforms to accessibility standards, see Accessibility in Visual Studio and ASP.NET and ASP.NET Controls and Accessibility.
