Declaration

Description
SetCheckboxState is a method used to set the checked, unchecked,
or grayed state for a check box in the cell specified by
ACol and
ARow.
AState contains the state value applied to the
cell.
SetCheckboxState signals the OnSetCheckboxState event handler
(when assigned) to perform the actions needed to change the value in the
cell. If DefaultDrawing is enabled for the control, the
InvalidateCell method is called and causes the cell to be redrawn.
No actions are performed in the method when OnSetCheckboxState has not been assigned.
SetCheckboxState is called from the ToggleCheckbox method to apply
the new state value for the CheckBox.
