How to set the Font of Content present in the GroupBox in C#?

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 font of the text present in the GroupBox in the form using Font Property. You can set this property in two different ways:

1. Design-Time: It is the easiest way to set the font 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 to 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 font of the GroupBox as shown in the below image:

  

  Output:

  
  
  

  

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

public virtual System.Drawing.Font Font { get; set; }

Here, Font represents the font of the content present in the GroupBox. The following steps show how to set the font 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(); 
  

• Step 2: After creating GroupBox, set the Font property of the GroupBox provided by the GroupBox class.

  // Setting the font
  gbox.Font = new Font("Colonna MT", 12);
  

• 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:
