Here is the code:

ComboBox1 has values of number of years.

For dates, use DateTime.Now.AddDays(14)

For Months, use DateTime.Now.AddMonths(14)

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 DateProject
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
void ChangeDate()
{
DateTime dateTime = dateTimePicker1.Value;
int count = 0;
if (comboBox1.SelectedItem != null)
{
count = Convert.ToInt32(comboBox1.SelectedItem.ToString());
}
DateTime addYears = dateTime.AddYears(count);
dateTimePicker2.Value = addYears;
}
private void Form1_Load(object sender, EventArgs e)
{

comboBox1.Items.Insert(0,"1");
comboBox1.Items.Insert(1, "2");
comboBox1.Items.Insert(2, "3");
ChangeDate();
dateTimePicker1.ValueChanged += new EventHandler(dateTimePicker1_ValueChanged);
comboBox1.SelectedIndexChanged += new EventHandler(comboBox1_SelectedIndexChanged);
}

void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ChangeDate();
}

void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
ChangeDate();
}
}
}

Let me know if you have any questions.

Here now we have 3 combo boxes one is for displaying years other one for month other one for days.

using System;

using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace DateProject
{
public partial class Form1 : Form
{
private int _mode = 0;
public Form1()
{
InitializeComponent();
}
void ChangeDate()
{
DateTime dateTime = dateTimePicker1.Value;
int yearCount = 0;
int monthCount = 0;
int dayCount = 0;
if (comboYears.SelectedItem != null)
{
yearCount = Convert.ToInt32(comboYears.SelectedItem.ToString());
}
if (comboMonths.SelectedItem != null)
{
monthCount = Convert.ToInt32(comboMonths.SelectedItem.ToString());
}
if (comboDays.SelectedItem != null)
{
dayCount = Convert.ToInt32(comboDays.SelectedItem.ToString());
}
DateTime addDate;
if ((yearCount>0)&&(_mode == 1))
{
addDate = dateTime.AddYears(yearCount);
}
else if ((monthCount>0)&&(_mode == 2))
{
addDate = dateTime.AddMonths(monthCount);
}
else if ((yearCount>0)&&(_mode == 3))
{
addDate = dateTime.AddDays(dayCount);
}
else
{
addDate = dateTime.AddDays(0);
}

dateTimePicker2.Value = addDate;
}
private void Form1_Load(object sender, EventArgs e)
{
try
{
_mode = 0;
label7.Text = "First DateTimePicker";
comboYears.Items.Insert(0,"1");
comboYears.Items.Insert(1, "2");

comboMonths.Items.Insert(2, "3");
comboDays.Items.Insert(0, "1");
comboDays.Items.Insert(1, "2");
comboDays.Items.Insert(2, "3");
ChangeDate();
dateTimePicker1.ValueChanged += new EventHandler(dateTimePicker1_ValueChanged);
comboYears.SelectedIndexChanged += new EventHandler(comboBox1_SelectedIndexChanged);
comboMonths.SelectedIndexChanged += new EventHandler(comboMonths_SelectedIndexChanged);
comboDays.SelectedIndexChanged += new EventHandler(comboDays_SelectedIndexChanged);

}
catch (Exception exc)
{
MessageBox.Show(exc.Message);
}
}

void comboDays_SelectedIndexChanged(object sender, EventArgs e)
{
try
{

}

void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
try
{

label7.Text = "Year";
ChangeDate();
}
catch(Exception exc)
{

Please validate my understanding. You have two date pickers and if you set today's date and select a 2 year period then you would like to see the date after 2 years. Correct?
