Hi Garth. Hope this helps! Application Starts and all dates are the same I change top date picker to date July 30. Date 2 is equal or greater than Date 1 Date 3 is equal or greater than Date 2 Date 4 is equal or greater than Date 3 Code: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Data.SqlClient; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using System.IO; namespace Sandbox2 { public partial class MyMainForm : Form { public MyMainForm() { InitializeComponent(); } private void MyMainForm_Load( object sender, EventArgs e) { } private void dtpDate1_ValueChanged( object sender, EventArgs e) { DateTime dt = dtpDate1.Value; dtpDate2.Value = dt.AddDays(1); dtpDate3.Value = dt.AddDays(2); dtpDate4.Value = dt.AddDays(3); } } } Alright, Have a great day.

James, I tried the code and when I set the first date the rest of the dates will not change. Did I type in something wrong? Garth 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; using System.IO; namespace DateTimePicker { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { } private void dateTimePicker1_ValueChanged(object sender, EventArgs e) { DateTime dt = dateTimePicker1.Value; dateTimePicker2.Value = dt.AddDays(1); dateTimePicker3.Value = dt.AddDays(2); dateTimePicker4.Value = dt.AddDays(3); } } }

I wish I could upload an image for the response but I do not know how... I am not sure how to explain this. I just have 4 datetimepickers on my form1. I have no code whatsoever

The question was little bit confusion for me. It would be useful if you provide sample data of datetimepicker and required expected output

DateTimePicker1 >= DateTimePicker2
