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.
