  for example current month is jan then in my month dropdown month is : december,jan(select), feb and year is 2013

  I think you are confused in what you supposed to do.

  How can you decide after user selects december, it is Dec-2012 / Dec-2013.

  Do simple thing use two dropdowns of Month and Year and let user choose Month and Year among them.

  Or let user choose any month and consider it as of 2013, which will again create problem for back dated entries. Use above approach..

  Good Luck

  Hi,

  I got your problem, you can get this done by checking the selected index and then check the name of the month. Try as below,

  if (ddlmonth.SelectedItem.Value.ToString() == "December" && ddlmonth.SelectedIndex==0)
  {
  ddlyear.Items.Insert(0, new ListItem(DateTime.Now.AddYears(-1).ToString("yyyy")));
  // ddlyear.SelectedItem.Value = DateTime.Now.AddYears(-1).ToString("yyyy");
  ddlyear.SelectedIndex = 0;
  ddlyear.Enabled = false;}

  else
  {
  ddlyear.Items.Insert(0, new ListItem(DateTime.Now.Year.ToString()));
  ddlyear.SelectedIndex = 0;
  ddlyear.Enabled = false;
  }}
