The CheckBoxCell class is a special type of Cell used to display a check box control. The CheckBoxCell implements the IEditingCell interface, so it can be edited without an editing control. The user can edit the value of the cell by clicking or pressing the space key when the CheckBoxCell is the current cell.
Notes to Inheritors:
When you derive from CheckBoxCell and add new properties to the derived class, be sure to override the Clone method to copy the new properties during cloning operations. You should also call the base class's Clone method so that the properties of the base class are copied to the new cell.
