How to set Up and Down Button in DateTimePicker in C#?

In Windows Forms, the DateTimePicker control is used to select and display date/time with a specific format in your form. In DateTimePicker control, you are allowed to set a spin button control or up-down control in the DateTimePicker to adjust date/time using the ShowUpDown Property. If the value of this property is set to true, then an up-down control display in the DateTimePicker control, otherwise, false. You can set this property in two different ways:

1. Design-Time: It is the easiest way to set an up-down control in the DateTimePicker 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 DateTimePicker 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 DateTimePicker and set an up-down control in the DateTimePicker 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 an up-down control in the DateTimePicker control programmatically with the help of given syntax:

public bool ShowUpDown { get; set; }

The value of this property is of System.Boolean type, either true or false. The default value of this property is false. The following steps show how to set an up-down control in the DateTimePicker dynamically:

Step 1: Create a DateTimePicker using the DateTimePicker() constructor is provided by the DateTimePicker class.
```
// Creating a DateTimePicker
DateTimePicker dt = new DateTimePicker();
```
Step 2: After creating DateTimePicker, set the ShowUpDown property of the DateTimePicker provided by the DateTimePicker class.
```
// Setting the ShowUpDown property
dt.ShowUpDown = true;
```
Step 3: And last add this DateTimePicker control to the form using the following statement:
```
// Adding this control to the form
this.Controls.Add(dt);
```

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 WindowsFormsApp49 { 
  
public partial class Form1 : Form { 
  
    public Form1() 
    { 
        InitializeComponent(); 
    } 
  
    private void Form1_Load(object sender, EventArgs e) 
    { 
        // Creating and setting the  
        // properties of the Label 
        Label lab = new Label(); 
        lab.Location = new Point(183, 162); 
        lab.Size = new Size(172, 20); 
        lab.Text = "Select Time"; 
        lab.Font = new Font("Comic Sans MS", 12); 
  
        // Adding this control to the form 
        this.Controls.Add(lab); 
  
        // Creating and setting the  
        // properties of the DateTimePicker 
        DateTimePicker dt = new DateTimePicker(); 
        dt.Location = new Point(360, 162); 
        dt.Size = new Size(292, 26); 
        dt.MaxDate = new DateTime(2500, 12, 20); 
        dt.MinDate = new DateTime(1753, 1, 1); 
        dt.Format = DateTimePickerFormat.Time; 
        dt.Name = "MyPicker"; 
        dt.Font = new Font("Comic Sans MS", 12); 
        dt.ShowUpDown = true; 
  
        // Adding this control 
        // to the form 
        this.Controls.Add(dt); 
    } 
} 
} 

Output:
