C# | GroupBox Class

Introduction

The computer language C# (pronounced "See Sharp") is modern, object-oriented, and type-safe. C# allows programmers to create a wide range of secure and reliable programmes for use in.

A GroupBox is a frame display surrounding a set of controls and includes an optional title. A GroupBox can also be used to categorize the controls in a group. The GroupBox class represents the windows group box and has a variety of attributes, methods, and events. A group box is mainly used to organize a logical group of RadioButton controls.

There are two ways to create a GroupBox:

Design-Time

Run-Time

Design-Time

It's the most straightforward approach to making a GroupBox. We can create a GroupBox control using a Forms designer at design time.

To create a GroupBox control at design time, we follow some step which is shown below:

Step 1: As demonstrated in the figure below, create windows form with the help of the following steps:

Open Visual Studio → File → New → Project →WindowsFormApp → Project Name
 

Step 2: drag and drop a GroupBox onto a Form from the toolbox.

Step 3: After you drag and drop a GroupBox on a Form, the GroupBox looks like this.

Step 4: Add properties based on your requirement.

Run-Time 

Using the syntax provided by the GroupBox class, you can build a GroupBox programmatically in this function. The steps below demonstrate how to dynamically set the create GroupBox:

Step 1: Creating a GroupBox. 

                GroupBox box = new GroupBox();

Step 2: Set the property of the GroupBox.

                box.Location = new Point(180, 146);

                box.Size = new Size(450, 150);

                box.Text = "Gender";

                box.Name = "Mybox";

Step 3: Add this GroupBox control to the form. 

                this.Controls.Add(box);

Step 4: Add other controls on the GroupBox.

                box.Controls.Add(b1);

Example:

namespace WinFormsApp3
{
    partial class Form1
    {
        /* <summary>
         Required designer variable.
         </summary>  */        
         private System.ComponentModel.IContainer components = null;


        /* <summary>
          Clean up any resources being used.
         </summary>
         <param name="disposing">true if managed resources should be disposed;otherwise, false.</param>  */
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }


        #region Windows Form Designer generated code


        /* <summary>
          Required method for Designer support - do not modify the contents of this method with the code editor.
         </summary> */
        private void InitializeComponent()
        {
            // Creating and setting properties of the GroupBox
            GroupBox box = new GroupBox();
            {
                box.Location = new Point(180, 146);
                box.Size = new Size(450, 150);
                box.Text = "Gender";
                box.Name = "Mybox";
            };
            // Adding Groupbox in the form
            this.Controls.Add(box);
            // Creating and setting properties of the CheckBox
            CheckBox b1 = new CheckBox();
            {
                b1.Location = new Point(40, 40);
                b1.Size = new Size(100, 50);
                b1.Text = "Male";
            };
            // Adding this control to the GroupBox
            box.Controls.Add(b1);
            // Creating and setting properties of the CheckBox
            CheckBox b2 = new CheckBox();
            {
                b2.Location = new Point(160, 40);
                b2.Size = new Size(100, 50);
                b2.Text = "Female";
            };
            // Adding this control to the GroupBox
            box.Controls.Add(b2);
            // Creating and setting properties of the CheckBox
            CheckBox b3 = new CheckBox();
            {
                b3.Location = new Point(320, 40);
                b3.Size = new Size(100, 50);
                b3.Text = "Others";
            };
            // Adding this control to the GroupBox
            box.Controls.Add(b3);
        }
        #endregion
    }
