C# | DateTimePicker Class - GeeksforGeeks

In Windows Forms, the DateTimePicker control is used to select and display the date/time with a specific format in your form. The FlowLayoutPanel class is used to represent windows DateTimePicker control and also provide different types of properties, methods, and events. It is defined under System.Windows.Forms namespace. You can create two different types of DateTimePicker, as a drop-down list with a date represented in the text, or as a calendar which appears when you click on the down-arrow next to the given list. In C#, you can create a DateTimePicker in the windows form by using two different ways:
1. Design-Time: It is the easiest way to create a DateTimePicker control 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 to modify DateTimePicker according to your requirement.Output:
Output:
2. Run-Time: It is a little bit trickier than the above method. In this method, you can create a DateTimePicker programmatically with the help of syntax provided by the DateTimePicker class. The following steps show how to set the create DateTimePicker dynamically:
Step 1: Create a DateTimePicker using the DateTimePicker() constructor is provided by the DateTimePicker class.// Creating a DateTimePicker
DateTimePicker d = new DateTimePicker();

// Creating a DateTimePicker
DateTimePicker d = new DateTimePicker();

Step 2: After creating a DateTimePicker, set the properties of the DateTimePicker provided by the DateTimePicker class.// Setting the location of the DateTimePicker
d.Location = new Point(360, 162); 

// Setting the size of the DateTimePicker
d.Size = new Size(292, 26); 

// Setting the maximum date of the DateTimePicker
d.MaxDate = new DateTime(2500, 12, 20); 

// Setting the minimum date of the DateTimePicker
d.MinDate = new DateTime(1753, 1, 1); 

// Setting the format of the DateTimePicker
d.Format = DateTimePickerFormat.Long; 

// Setting the name of the DateTimePicker
d.Name = "MyPicker"; 

// Setting the font of the DateTimePicker
d.Font = new Font("Comic Sans MS", 12);

// Setting the visibility of the DateTimePicker 
d.Visible = true; 

// Setting the value of the DateTimePicker
d.Value = DateTime.Today; 

// Setting the location of the DateTimePicker
d.Location = new Point(360, 162); 

// Setting the size of the DateTimePicker
d.Size = new Size(292, 26); 

// Setting the maximum date of the DateTimePicker
d.MaxDate = new DateTime(2500, 12, 20); 

// Setting the minimum date of the DateTimePicker
d.MinDate = new DateTime(1753, 1, 1); 

// Setting the format of the DateTimePicker
d.Format = DateTimePickerFormat.Long; 

// Setting the name of the DateTimePicker
d.Name = "MyPicker"; 

// Setting the font of the DateTimePicker
d.Font = new Font("Comic Sans MS", 12);

// Setting the visibility of the DateTimePicker 
d.Visible = true; 

// Setting the value of the DateTimePicker
d.Value = DateTime.Today; 

Step 3: And last add this DateTimePicker control to the form and also add other controls on the DateTimePicker using the following statements:// Adding this control 
// to the form 
this.Controls.Add(d); 
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 WindowsFormsApp48 {  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 l = new Label();        l.Location = new Point(183, 162);        l.Size = new Size(172, 20);        l.Text = "Select Date and Time";        l.Font = new Font("Comic Sans MS", 12);          // Adding this control        // to the form        this.Controls.Add(l);          // Creating and setting the        // properties of the DateTimePicker        DateTimePicker d = new DateTimePicker();        d.Location = new Point(360, 162);        d.Size = new Size(292, 26);        d.MaxDate = new DateTime(2500, 12, 20);        d.MinDate = new DateTime(1753, 1, 1);        d.Format = DateTimePickerFormat.Long;        d.Name = "MyPicker";        d.Font = new Font("Comic Sans MS", 12);        d.Visible = true;        d.Value = DateTime.Today;          // Adding this control        // to the form        this.Controls.Add(d);    }}}Output:
// Adding this control 
// to the form 
this.Controls.Add(d); 

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 WindowsFormsApp48 {  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 l = new Label();        l.Location = new Point(183, 162);        l.Size = new Size(172, 20);        l.Text = "Select Date and Time";        l.Font = new Font("Comic Sans MS", 12);          // Adding this control        // to the form        this.Controls.Add(l);          // Creating and setting the        // properties of the DateTimePicker        DateTimePicker d = new DateTimePicker();        d.Location = new Point(360, 162);        d.Size = new Size(292, 26);        d.MaxDate = new DateTime(2500, 12, 20);        d.MinDate = new DateTime(1753, 1, 1);        d.Format = DateTimePickerFormat.Long;        d.Name = "MyPicker";        d.Font = new Font("Comic Sans MS", 12);        d.Visible = true;        d.Value = DateTime.Today;          // Adding this control        // to the form        this.Controls.Add(d);    }}}
