A radio button or option button is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options. The singular property of a radio button makes it distinct from checkboxes, where the user can select and unselect any number of items.

Because radio buttons are mutually exclusive, group them inside a RadioGroup . The system ensures that only one radio button within a group can be selected at a time.

You group radio buttons by drawing them inside a container such as a Panel control, a GroupBox 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.

You can enable and disable the radio button by using the disabled property of HTML DOM. Set this property to true (disable=true) to disable the radio button in JavaScript.

Step 1 The user can focus on the radio button list by using the TAB key of the keyboard. Step 2 The user can navigate through the radio buttons list by using the UP/DOWN arrow keys of the keyboard. Step 3The user can select the value of the radio buttons list within the issue by using the ENTER key of the keyboard.
