Radio button

Radio buttons allow users to choose an option in a group. The user is presented with a circle that is either empty or checked followed by a label indicating the setting that is being edited.

Radio buttons are groupable. If they are on the main form, they are naturally exclusive, meaning that you can't have more than one selected simultaneously. However, if you add them to a frame, they can be selected independently from radio button controls outside the frame.

At design time, you can set its Value property to -1 to have it saved checked.
