How to add datetime picker in Datagridview in C#

You may download the attached sample project for more understanding

For a demo purpose I created a class:

    class MyData
    {
        public int ID { get; set; }
        public DateTime Date { get; set; }
        public string Name { get; set; }

        public MyData(int id, DateTime dt, string name)
        {
            ID = id;
            Date = dt;
            Name = name;
        }
    }

Then on the main Form, I am creating a TestData and binding into DataGrid After that on CellClick event, a DateTimePicker Control is being generated programmatically See the code below:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace CalanderInDataGridView
{
    public partial class MainForm : Form
    {
        DateTimePicker  oDateTimePicker ;

        public MainForm()
        {
            InitializeComponent();
        }

        private void MainForm_Load(object sender, EventArgs e)
        {
            // Creating a Test data
            List  oMyDataList = new List();

            MyData obj1 = new MyData(1, DateTime.Now, "John");
            MyData obj2 = new MyData(2, DateTime.Now, "Sam");
            MyData obj3 = new MyData(3, DateTime.Now, "Ram");

            oMyDataList.Add(obj1);
            oMyDataList.Add(obj2);
            oMyDataList.Add(obj3);

            // Binding as a Data Source into DataGridView
            dataGridView1.DataSource = oMyDataList;
        }

        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            // If any cell is clicked on the Second column which is our date Column
            if (e.ColumnIndex == 1)
            {
                oDateTimePicker = new DateTimePicker();  //DateTimePicker 

                //Adding DateTimePicker control into DataGridView
                dataGridView1.Controls.Add(oDateTimePicker);

                // Intially made it invisible
                oDateTimePicker.Visible = false;

                // Setting the format (i.e. 2014-10-10)
                oDateTimePicker.Format = DateTimePickerFormat.Short;  //

                oDateTimePicker.TextChanged += new EventHandler(dateTimePicker_OnTextChange);  

                // Now make it visible
                oDateTimePicker.Visible = true;

                // It returns the retangular area that represents the Display area for a cell
                 Rectangle oRectangle = dataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);

                //Setting area for DateTimePicker Control
                oDateTimePicker.Size = new Size(oRectangle.Width, oRectangle.Height);

                // Setting Location
                oDateTimePicker.Location = new Point(oRectangle.X, oRectangle.Y);

                oDateTimePicker.CloseUp += new EventHandler(oDateTimePicker_CloseUp);
            }
        }

        private void dateTimePicker_OnTextChange(object sender, EventArgs e)
        {
            dataGridView1.CurrentCell.Value = oDateTimePicker.Text.ToString();
        }

        void oDateTimePicker_CloseUp(object sender, EventArgs e)
        {
            oDateTimePicker.Visible = false;
        }
    }

    class MyData
    {
        public int ID { get; set; }
        public DateTime Date { get; set; }
        public string Name { get; set; }

        public MyData(int id, DateTime dt, string name)
        {
            ID = id;
            Date = dt;
            Name = name;
        }
    }
}

Hope it will help
