Hi Thulasiram Pakala, I did it for check it, works as you expect. istead of if condition you can use switch condition. by reviewing my code you can get different idea to do the same with may be lesser line of code. using System; using System.Windows.Forms; namespace currentMonthWithPreviuosTwo { public partial class Form1 : Form { public Form1() { InitializeComponent(); } int currentMonth = System.DateTime.Now.Month; private void Form1_Load(object sender, EventArgs e) { if (currentMonth == 1) { comboBox1.Items.Add(1); comboBox1.Items.Add(12); comboBox1.Items.Add(11); } else if (currentMonth == 2) { comboBox1.Items.Add(2); comboBox1.Items.Add(1); comboBox1.Items.Add(12); } else if (currentMonth == 3) { comboBox1.Items.Add(3); comboBox1.Items.Add(2); comboBox1.Items.Add(1); } else if (currentMonth == 4) { comboBox1.Items.Add(4); comboBox1.Items.Add(3); comboBox1.Items.Add(2); } else if (currentMonth == 5) { comboBox1.Items.Add(5); comboBox1.Items.Add(4); comboBox1.Items.Add(3); } else if (currentMonth == 6) { comboBox1.Items.Add(6); comboBox1.Items.Add(5); comboBox1.Items.Add(4); } else if (currentMonth == 7) { comboBox1.Items.Add(7); comboBox1.Items.Add(6); comboBox1.Items.Add(5); } else if (currentMonth == 8) { comboBox1.Items.Add(8); comboBox1.Items.Add(7); comboBox1.Items.Add(6); } else if (currentMonth == 9) { comboBox1.Items.Add(9); comboBox1.Items.Add(8); comboBox1.Items.Add(7); } else if (currentMonth == 10) { comboBox1.Items.Add(10); comboBox1.Items.Add(11); comboBox1.Items.Add(12); } else if (currentMonth == 11) { comboBox1.Items.Add(11); comboBox1.Items.Add(12); comboBox1.Items.Add(1); } else if (currentMonth == 12) { comboBox1.Items.Add(12); comboBox1.Items.Add(11); comboBox1.Items.Add(10); } } private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) { comboBox2.Items.Clear(); int combMo = Convert.ToInt32(comboBox1.Text); if (combMo == 1) { comboBox2.Items.Add(System.DateTime.Now.Year); comboBox2.Items.Add(System.DateTime.Now.Year-1); } else if (combMo == 2 || combMo == 3 || combMo == 4 || combMo == 5 || combMo == 6 || combMo == 7 || combMo == 8 || combMo == 9 || combMo == 10 || combMo == 11 || combMo == 12) { comboBox2.Items.Add(System.DateTime.Now.Year); } } } }
