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

  • Last Updated : 30 Jun, 2019

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 adjust the size of the RadioButton using the Size Property of the RadioButton. This property represents both the height and width of the RadioButton in pixels. You can set this property in two different ways:

1. Design-Time: It is the easiest way to adjust the size 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 adjust the size of RadioButton.


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

public System.Drawing.Size Size { get; set; }

Here, Size indicates the height and width in pixels. The following steps show how to adjust the size 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 Size property of the RadioButton provided by the RadioButton class.
    // Setting the size of the radio button
     r1.Size = new Size(100, 40);
  • Step 3: And last add this RadioButton control to the form using Add() method.
    // Add this radio button to the form

        private void Form1_Load(object sender, EventArgs e)
            // Creating and setting label
            Label l = new Label();
            l.AutoSize = true;
            l.Location = new Point(176, 40);
            l.Text = "Select Post";
            // Adding this label to the form
            // Creating and setting the 
            // properties of the RadioButton
            RadioButton r1 = new RadioButton();
            r1.Size = new Size(100, 40);
            r1.Text = "Intern";
            r1.Location = new Point(286, 40);
            r1.TextAlign = ContentAlignment.MiddleLeft;
            // Adding this label to the form
            // Creating and setting the 
            // properties of the RadioButton
            RadioButton r2 = new RadioButton();
            r2.Text = "Team Leader";
            r2.Location = new Point(450, 40);
            r2.TextAlign = ContentAlignment.MiddleLeft;
            r2.Size = new Size(100, 40);
            // Adding this label to the form
