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 appearance of the RadioButton in your form using the Appearance property of the RadioButton. Appearance property is set to normal, then it behaves like the normal RadioButton and if the Appearance Property set to the button, then it will work like a toggle button. The default value of this property is Normal. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the appearance of the RadioButton as shown in the following steps:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the appearance of the RadioButton control programmatically with the help of given syntax:
public System.Windows.Forms.Appearance Appearance { get; set; }
Here, Appearance represents the Appearance value. There are two types of Appearance value available one is Normal and another one is Button. It will throw an InvalidEnumArgumentException if the value assigned to this property does not belong to Appearance value. The following steps show how to set the appearance 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 Appearance property of the RadioButton provided by the RadioButton class.
// Setting the appearance of the radio button
r1.Appearance = Appearance.Button;
- 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)
{
Label l = new Label();
l.AutoSize = true ;
l.Location = new Point(176, 40);
l.Text = "Select Your Branch" ;
l.ForeColor = Color.DarkGreen;
this .Controls.Add(l);
RadioButton r1 = new RadioButton();
r1.AutoSize = true ;
r1.Text = "CSE" ;
r1.Location = new Point(286, 39);
r1.ForeColor = Color.DarkGreen;
r1.Appearance = Appearance.Button;
this .Controls.Add(r1);
RadioButton r2 = new RadioButton();
r2.AutoSize = true ;
r2.Text = "ECE" ;
r2.Location = new Point(356, 40);
r2.ForeColor = Color.DarkGreen;
r2.Appearance = Appearance.Normal;
this .Controls.Add(r2);
}
}
}
