Recently in one of my project I needed to have an option to display the DateTimePicker allowing user to pick both the date and the time. When I drag the control onto the form however I could only chooses the date or the time but not both. Well actually you can have both, all you have to do is use the CustomFormat property.

Here‘s how:

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 WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

            this.dateTimePicker1.CustomFormat = "MM/dd/yyyy HH:mm";

            this.dateTimePicker1.Format = System.Windows.Forms.DateTimePickerFormat.Custom;

        }

    }

}
