MenuItem.Enabled Property

 

Gets or sets a value that indicates whether the MenuItem object is enabled, allowing the item to display a pop-out image and any child menu items.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

[BrowsableAttribute(true)]
public bool Enabled { get; set; }

Property Value

Type: System.Boolean

true if the menu item is enabled; otherwise, false.

When this property is set to false, the menu item is disabled and no pop-out image indicating child items is displayed. Setting this property to false for a menu item essentially makes the menu item the end of that node, where no further levels are shown off of that node. The default value is true.

If you want the menu item to show any child items, but to not be "clickable" itself, use the Selectable property and set it to false.

The following example demonstrates how a menu item with the Enabled property set to false appears and functions in a menu.
