Description

Represents a Windows radio button.

Remarks

When the user selects one radio button within a group, the others clear automatically. All RadioButton controls in a given container, such as a Form, constitute a group. To create multiple groups on one form, place each group in its own container, such as a GroupBox control.

RadioButton and CheckBox controls have a similar function: they offer choices a user can select or clear. The difference is that multiple CheckBox controls can be selected at the same time, but radio buttons are mutually exclusive.

Use the Checked property to get or set the state of a RadioButton. The radio button's appearance can be altered to appear as a toggle-style button or as a standard radio button by setting the Appearance property.

Note: The radio button is sometimes referred to as an option button.
