Windows Forms radio button and groupBox controls in in -- Windows Forms Application c#

Windows Forms radio button controls are designed to give users a choice among two or more settings, of which only one can be assigned to a procedure or object. For example, a group of  radio button  controls may display a choice of package carriers for an order, but only one of the carriers will be used. Therefore only one radio button  at a time can be selected, even if it is a part of a functional group.

You group radio buttons by drawing them inside a container such as a  panel control, a group box control, or a form. All radio buttons that are added directly to a form become one group. To add separate groups, you must place them inside panels or group boxes. For more information about panels or group boxes.
