Try something like this: public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender EventArgs e) { int[] years = { 2011 2012 2013 2014 }; // or whatever comboBox1.DataSource = years; string[] months = { January February March April May June July August September October November December }; comboBox2.DataSource = months; comboBox1.SelectedIndex = 3; // say comboBox2.SelectedIndex = 0; } private void comboBox1_SelectedIndexChanged(object sender EventArgs e) { GetDays(); } private void comboBox2_SelectedIndexChanged(object sender EventArgs e) { GetDays(); } private void GetDays() { int year = 0; int month = 0; if (comboBox1.SelectedIndex > -1 && comboBox2.SelectedIndex > -1) { year = int.Parse(comboBox1.SelectedItem.ToString()); month = comboBox2.SelectedIndex + 1; } else { return; } int daysInMonth = DateTime.DaysInMonth(year month); string[] days = new string[daysInMonth]; DateTime dt = new DateTime(year month 1); for (int i = 0; i { days[i] = String.Format({0 -2} {1} i + 1 dt.DayOfWeek); dt = dt.AddDays(1); } comboBox3.DataSource = days; comboBox3.SelectedIndex = 0; } }
