How to Set the Visibility of the GroupBox in C#? - GeeksforGeeks

02 Aug, 2019
In Windows Forms, GroupBox is a container which contains multiple controls in it and the controls are related to each other. Or in other words, GroupBox is a frame display around a group of controls with a suitable optional title. Or a GroupBox is used to categorize the related controls in a group. In GroupBox, you can set the visibility of the GroupBox in the form using Visible Property.If the value of this property is set to true, then the GroupBox is visible on the screen, and if the value of this property is set to false, then the GroupBox does not visible on the screen. The default value of this property is true. You can set this property in two different ways:
1. Design-Time: It is the easiest way to set the visibility of the GroupBox 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: Next, drag and drop the GroupBox control from the toolbox on the form as shown in the below image:
Step 3: After drag and drop you will go to the properties of the GroupBox and set the visibility of the GroupBox as shown in the below image:Output:
Output:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the visibility of the GroupBox control programmatically with the help of given syntax:
public override string Text { get; set; }
The following steps show how to set the visibility of the GroupBox dynamically:
Step 1: Create a GroupBox using the GroupBox() constructor is provided by the GroupBox class.// Creating a GroupBox
GroupBox gbox = new GroupBox(); 

// Creating a GroupBox
GroupBox gbox = new GroupBox(); 

Step 2: After creating GroupBox, set the Visible property of the GroupBox provided by the GroupBox class.// Setting visibility
gbox.Visible = true;

// Setting visibility
gbox.Visible = true;

Step 3: And last add this GroupBox control to the form and also add other controls on the GroupBox using the following statements:// Adding groupbox in the form
this.Controls.Add(gbox);

and 

// Adding this control 
// to the GroupBox
gbox.Controls.Add(c2);
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 WindowsFormsApp46 {  public partial class Form1 : Form {      public Form1()    {        InitializeComponent();    }      private void Form1_Load(object sender, EventArgs e)    {        // Creating and setting         // properties of the GroupBox        GroupBox gbox = new GroupBox();        gbox.Location = new Point(179, 145);        gbox.Text = "Select Gender";        gbox.Name = "Mybox";        gbox.Font = new Font("Colonna MT", 12);        gbox.Visible = true;        gbox.AutoSize = true;        gbox.AutoSizeMode = AutoSizeMode.GrowAndShrink;          // Adding groupbox in the form        this.Controls.Add(gbox);          // Creating and setting         // properties of the CheckBox        CheckBox c1 = new CheckBox();        c1.Location = new Point(40, 42);        c1.Size = new Size(69, 20);        c1.Text = "Male";          // Adding this control         // to the GroupBox        gbox.Controls.Add(c1);          // Creating and setting         // properties of the CheckBox        CheckBox c2 = new CheckBox();        c2.Location = new Point(183, 39);        c2.Size = new Size(79, 20);        c2.Text = "Female";          // Adding this control         // to the GroupBox        gbox.Controls.Add(c2);    }}}Output:
// Adding groupbox in the form
this.Controls.Add(gbox);

and 

// Adding this control 
// to the GroupBox
gbox.Controls.Add(c2);

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 WindowsFormsApp46 {  public partial class Form1 : Form {      public Form1()    {        InitializeComponent();    }      private void Form1_Load(object sender, EventArgs e)    {        // Creating and setting         // properties of the GroupBox        GroupBox gbox = new GroupBox();        gbox.Location = new Point(179, 145);        gbox.Text = "Select Gender";        gbox.Name = "Mybox";        gbox.Font = new Font("Colonna MT", 12);        gbox.Visible = true;        gbox.AutoSize = true;        gbox.AutoSizeMode = AutoSizeMode.GrowAndShrink;          // Adding groupbox in the form        this.Controls.Add(gbox);          // Creating and setting         // properties of the CheckBox        CheckBox c1 = new CheckBox();        c1.Location = new Point(40, 42);        c1.Size = new Size(69, 20);        c1.Text = "Male";          // Adding this control         // to the GroupBox        gbox.Controls.Add(c1);          // Creating and setting         // properties of the CheckBox        CheckBox c2 = new CheckBox();        c2.Location = new Point(183, 39);        c2.Size = new Size(79, 20);        c2.Text = "Female";          // Adding this control         // to the GroupBox        gbox.Controls.Add(c2);    }}}
