Description


CheckBox represents a check box that can be on (checked) or off (unchecked). The user can check the box to select the option, or uncheck it to deselect the option. If necessary, the component can have three states, such as On, Off and Grayed, to do this, set the AllowGrayed component property to True.


As a rule, this component is assigned to a specific database field through the TableName and FieldName properties.
