property Items.EnableItem(Item as HITEM) as Boolean

Returns or sets a value that determines whether a item can respond to user-generated events.

TypeDescription
Item as HITEM A long expression that indicates the item's handle.
Boolean A boolean expression that indicates whether the item is enabled or disabled.

Once that an item was disabled all the cells of that item are disabled, so the CellEnabled property has no effect. Use the Enabled property to disable a column. The SelectableItem property specifies whether the user can select an item. A disabled item looks grayed, but it is selectable. For instance, the user can't change the check box state in a disabled item.
