OptionButton controls are used to display options, usually in option button groups, from which the user can choose one.
OptionButton
The OptionButton control has the following properties, methods, and events.
You group OptionButton controls by drawing them inside a container such as a Frame control or a form. To group OptionButton controls in a Frame, draw the Frame first, and then draw the OptionButton controls inside. All OptionButton controls within the same container act as a single group.
While OptionButton controls and CheckBox controls may appear to function similarly, there is an important difference: When a user selects an OptionButton, the other OptionButton controls in the same group are automatically unavailable. In contrast, any number of CheckBox controls can be selected.
