|Variant||A Variant expression that indicates the column's extra data.|
Use the Data property to assign an extra data to a column. The Data property is not used by the control, so you can hold any extra data associated to the column. You can use the RemoveColumn event to release the extra data that's associated to a column, in case it is required. Use the ItemData property to associate an extra data to an item. Use the CellData property to assign an extra data to a cell.
