How to set the Font of the RadioButton in C#?

In Windows Forms, RadioButton control is used to select a single option among the group of the options. For example, select your gender from the given list, so you will choose only one option among three options like Male or Female or Transgender. In Windows Forms, you are allowed to set the font of the content present in the RadioButton using the Font Property of the RadioButton. You can set this property in two different ways:

1. Design-Time: It is the easiest way to set the font of the RadioButton as shown in the following steps:

• Step 1: Create a windows form as shown in the below image:
  Visual Studio -> File -> New -> Project -> WindowsFormApp
  
• Step 2: Drag the RadioButton control from the ToolBox and drop it on the windows form. You are allowed to place a RadioButton control anywhere on the windows form according to your need.
  
• Step 3: After drag and drop you will go to the properties of the RadioButton control to set the font of the RadioButton.
  

  Output:
  

2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the font of the RadioButton control programmatically with the help of given syntax:

public virtual System.Drawing.Font Font { get; set; }

Here, Font represents the font of the content present in the RadioButton. The following steps show how to set the font of the RadioButton dynamically:

• Step 1: Create a radio button using the RadioButton() constructor is provided by the RadioButton class.

  // Creating radio button
  RadioButton r1 = new RadioButton();
  

• Step 2: After creating RadioButton, set the Font property of the RadioButton provided by the RadioButton class.

  // Setting the font of the radio button
  r1.Font = new Font("Berlin Sans FB", 12);
  

• Step 3: And last add this RadioButton control to the form using Add() method.

  // Add this radio button to the form
  this.Controls.Add(r1);
  

  Example:

  using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Data;
  using System.Drawing;
  using System.Linq;
  using System.Text;
  using System.Threading.Tasks;
  using System.Windows.Forms;
  
  namespace WindowsFormsApp21 {
  
  public partial class Form1 : Form {
  
      public Form1()
      {
          InitializeComponent();
      }
  
      private void Form1_Load(object sender,
                               EventArgs e)
      {
  
          // Creating and setting label
          Label l = new Label();
          l.AutoSize = true;
          l.Location = new Point(136, 40);
          l.Text = "Select Your Branch";
          l.ForeColor = Color.DarkGreen;
          l.Font = new Font("Berlin Sans FB", 12);
  
          // Adding this label to the form
          this.Controls.Add(l);
  
          // Creating and setting the
          // properties of the RadioButton
          RadioButton r1 = new RadioButton();
          r1.AutoSize = true;
          r1.Text = "CSE";
          r1.Location = new Point(286, 40);
          r1.ForeColor = Color.DarkGreen;
          r1.Font = new Font("Berlin Sans FB", 12);
  
          // Adding this label to the form
          this.Controls.Add(r1);
  
          // Creating and setting the
          // properties of the RadioButton
          RadioButton r2 = new RadioButton();
          r2.AutoSize = true;
          r2.Text = "ECE";
          r2.Location = new Point(356, 40);
          r2.ForeColor = Color.DarkGreen;
          r2.Font = new Font("Berlin Sans FB", 12);
  
          // Adding this label to the form
          this.Controls.Add(r2);
      }
  }
  }

  Output:
