for (int i = 1999; i < (DateTime.Now.Year + 1); i++)
{
   MarketDates DDLFromDate = new MarketDates();
   MarketDates DDLToDate = new MarketDates();

   DDLFromDate.DisplayDate = "JAN-" + i.ToString();
   DDLFromDate.SelectDate = i.ToString();
   LstFromDate.Add(DDLFromDate);

   DDLToDate.DisplayDate = "DEC-" + i.ToString();
   DDLToDate.SelectDate = i.ToString();
   LstToDate.Add(DDLToDate);
}

//Bind
DDLFromYear.DataTextField = "DisplayDate";
DDLFromYear.DataValueField = "SelectDate";
DDLFromYear.DataSource = LstFromDate;
DDLFromYear.DataBind();
     
DDLToYear.DataTextField = "DisplayDate";
