Week 4

In C#, a RadioButton is a control that allows users to select a single option from a set of choices. Multiple RadioButtons are grouped together, typically within a GroupBox or a Panel, so that only one button can be selected at a time.

    }

CheckBox

In C#, a CheckBox is a control that allows users to select or unselect an option. Unlike RadioButtons, CheckBoxes are independent of one another, so the user can check multiple options at the same time.
