## Description

OnCheckboxToggled is a TToggledCheckboxEvent property with the event handler signalled when the value for a check box-style cell is toggled. OnCheckboxToggled is triggered (when assigned) after the cell value has been changed and stored. OnCheckboxToggled is used in descendent classes which implement a method to toggle the value when the cell is clicked, like TCustomDrawGrid.
