# GroupBox

The `GroupBox` displays a frame around a group of controls with or without a caption. Use a `GroupBox` to logically group a collection of controls on a form. The `GroupBox` is a container control that can be used to define groups of controls.

A typical use for a group box is to contain a logical group of `RadioButton` controls. When you have two group boxes, each containing several radio buttons, each group of buttons is mutually exclusive, setting one option value per group.

You can add controls to the `GroupBox` using the `Add` method of the `Controls` property.
