Use this method to show any column controls for the columns in the grid. The control for a grid column is controlled via the TGridColumnControlType property. This method will change the ColumnControlVisible property to True.
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.
