How to Create Radio Buttons in WinForms C# projects

The following tutorial demonstrates creating two groups of radio buttons that are independently from each other. Choices of box are reflected in a label as they are selected.
  1. Drag and drop two group boxes from the control to the form you are designing.
  2. Drag and drop three Radio Buttons to the first group box. Set the text properties of the buttons as necessary, here are small, standard and large.
  3. Drag and drop three Radio Buttons on the second group box. Set the text properties of the buttons to Coffee, Tea, and Milk.
  4. Drag and drop a label to the form. Set the name of the label as status.
  5. Select all six Radio Buttons with the mouse while pressing down the shift key.
  6. Click the events tab on the button properties window.
  7. Double click the Toggle State Changed event to create an event handler. Replace the code with the following C# code.

void radioButton1_ToggleStateChanged(object sender, StateChangedEventArgs args)
status.Text = (sender as radioButton).Text + "is selected";
Run the .NET Forms application. You will find that the selections of radio buttons in the panel are independent of the radio button selections on the form. Radio Button determines the radio groups by the control parent. All Radio Buttons share the same parent like the Group Box, Panel or a Form will be part of one group.
