How to set Font of the NumericUpDown in C#?

In Windows Forms, NumericUpDown control is used to provide a Windows spin box or an up-down control which displays the numeric values. Or in other words, NumericUpDown control provides an interface which moves using up and down arrow and holds some pre-defined numeric value. In NumericUpDown control, you can set the font of the content present in the up-down control using the 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 NumericUpDown 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 NumericUpDown 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 NumericUpDown and set the font of the NumericUpDown 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 content present in the NumericUpDown 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 NumericUpDown control. The following steps show how to set the font of the NumericUpDown dynamically:

• Step 1: Create a NumericUpDown using the NumericUpDown() constructor is provided by the NumericUpDown class.

  // Creating a NumericUpDown
  NumericUpDown n = new NumericUpDown();
  

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

  // Setting the font
  n.Font = new Font("Bodoni MT", 12);
  

• Step 3: And last add this NumericUpDown control to the form using the following statement:

  // Adding NumericUpDown control on the form
  this.Controls.Add(n);
  

  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 WindowsFormsApp42 {
  
  public partial class Form1 : Form {
  
      public Form1()
      {
          InitializeComponent();
      }
  
      private void Form1_Load(object sender, EventArgs e)
      {
  
          // Creating and setting the
          // properties of the labels
          Label l1 = new Label();
          l1.Location = new Point(348, 61);
          l1.Size = new Size(215, 20);
          l1.Text = "Form";
          l1.Font = new Font("Bodoni MT", 12);
          this.Controls.Add(l1);
  
          Label l2 = new Label();
          l2.Location = new Point(242, 136);
          l2.Size = new Size(103, 20);
          l2.Text = "Enter Age";
          l2.Font = new Font("Bodoni MT", 12);
          this.Controls.Add(l2);
  
          // Creating and setting the
          // properties of NumericUpDown
          NumericUpDown n = new NumericUpDown();
          n.Location = new Point(386, 130);
          n.Size = new Size(126, 26);
          n.Font = new Font("Bodoni MT", 12);
          n.Value = 18;
          n.Minimum = 18;
          n.Maximum = 30;
          n.BackColor = Color.LightGreen;
          n.ForeColor = Color.DarkGreen;
          n.Increment = 1;
          n.Name = "MySpinBox";
  
          // Adding this control
          // to the form
          this.Controls.Add(n);
      }
  }
  }

  Output:
