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 alignment of the checkbox of the RadioButton using the CheckAlign Property of the RadioButton.
The value of this property is specified by the ContentAlignment enum, it contains 9 different types of values for checkbox alignment, i.e, BottomCenter, BottomLeft, BottomRight, MiddleCenter, MiddleLeft, MiddleRight, TopCenter, TopLeft, and TopRight. The default value of this property is MiddleLeft. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the alignment of the checkbox of the RadioButton as showing in the following steps:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the alignment of the checkbox of the RadioButton control programmatically with the help of given syntax:
public System.Drawing.ContentAlignment CheckAlign { get; set; }
Here, ContentAlignment is the ContentAlignment’s values. It will throw an InvalidEnumArgumentException if the value doesn’t belong to ContentAlignment’s values. The following steps show how to set the alignment of the checkbox 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 CheckAlign property of the RadioButton provided by the RadioButton class.
// Setting the alignment of the checkbox of the radio button
r1.CheckAlign = ContentAlignment.BottomCenter;
- 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 WindowsFormsApp23 {
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 Post" ;
this .Controls.Add(l);
RadioButton r1 = new RadioButton();
r1.AutoSize = true ;
r1.Text = "Intern" ;
r1.Location = new Point(286, 40);
r1.BackColor = Color.LightSteelBlue;
r1.Padding = new Padding(6, 6, 6, 6);
r1.CheckAlign = ContentAlignment.BottomCenter;
this .Controls.Add(r1);
RadioButton r2 = new RadioButton();
r2.Text = "Team Leader" ;
r2.Location = new Point(400, 40);
r2.AutoSize = true ;
r2.BackColor = Color.LightSteelBlue;
r2.Padding = new Padding(6, 6, 6, 6);
r2.CheckAlign = ContentAlignment.BottomCenter;
this .Controls.Add(r2);
}
}
}
