Indicates whether any grid column controls should be visible. The control for a grid column is controlled via the TGridColumnControlType property, and the grid column controls can be made visible by calling the ShowColumnControl method.
Even if the ColumnControlVisible property is True, it is possible that there won't be any active column controls because row selection is turned on for the grid control or the column doesn't use a control for display or editing. You can use the ColumnControlActive property to determine if any grid column controls are actually active.
