A check box control includes a selection box and a text label. When a user selects the control, a check mark appears in a check box. Typically, check boxes are used when you need to provide the end user with a limited number of choices from which any number may be selected, or when you want to present the end user with an option that may be turned on or off. Check boxes are also used to give the end user a Yes/No or True/False option.
