Comments

To freeze or un-freeze a cell, call L_DispContainerFreezeCell.

When a cell is frozen no actions using the mouse or the keyboard can be performed on the cell. Some cell properties can still be changed manually however, using L_DispContainerSetCellProperties, L_DispContainerSelectCell and L_DispContainerSetProperties. For more information on actions associated with a container, refer to Applying Actions.
