ListItem::Enabled Property
Gets or sets a value indicating whether the list item is enabled.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System::Booleantrue if the list item is enabled; otherwise, false. The default is true.
The Enabled property allows you to specify whether a ListItem control is enabled or disabled. A ListItem control that is disabled is dimmed to indicate that it cannot be selected. Use this property to disable a ListItem control in either a RadioButtonList control or a CheckBoxList control.

You cannot use this property to disable a ListItem control in a DropDownList control or ListBox control. |
The following example demonstrates how to use the Enabled property to programmatically disable list items in a RadioButtonList control. The first question asks the user to select the radio button that corresponds to the user's occupation. If the user indicates that he or she is not a developer, the list items in the second radio button list are disabled. The second question asks the user to select a primary programming language. This question is not relevant to a user that is not a developer.
