RadioButton Control

The RadioButton is used to select one option from the number of choices. If we want to select only one item from a related or group of items in the windows forms, we can use the radio button. The RadioButton is mutually exclusive that represents only one item is active and the remains unchecked in the form.

Let's create a RadioButton control in the VB.NET Windows by using the following steps.

Step 1: Drag the RadioButton control from the toolbox and drop it to the Windows form, as shown below.
