Remarks

This is a .NET interface derived from a COM coclass that is required by managed code for interoperability with the corresponding COM object. Use this derived interface to access all method, property, and event members of the COM object. However, if a method or event you want to use shares the same name under the same COM object, cast to the corresponding primary interface to call the method, and cast to the latest events interface to connect to the event. Refer to this topic for information about the COM object. For information about the method and property members of the COM object, see _OlkOptionButton. For information about the event members of the COM object, see OlkOptionButtonEvents_Event.

Before you use this control for the first time in the forms designer, add the Microsoft Outlook Option Button Control to the control toolbox. You can only add this control to a form region in an Outlook form using the forms designer.

The following is an example of an option button control at runtime. This control supports Microsoft Windows themes.

Typically more than one option button control is defined in a group. Each option button control in the group provides a single, mutually exclusive choice. Selecting one option button in the group will automatically remove the prior selection of another option button in the same group.
