Answer 1

Try This

public static string MiladiToShamsi(DateTime Date)   
      {   
           string Result;   
           string Year;
           string Month;
           string Day;
           # string Result, Year, Month, Day I don't know this works or not in asp.net 
           PersianCalendar FarsiDate = new PersianCalendar();   
            Year = FarsiDate.GetYear(Date).ToString();
            Month = (FarsiDate.GetMonth(Date) < 10 ? "0" + FarsiDate.GetMonth(Date).ToString() : FarsiDate.GetMonth(Date).ToString());
            Day = (FarsiDate.GetDayOfMonth(Date) < 10 ? "0" + FarsiDate.GetDayOfMonth(Date).ToString() : FarsiDate.GetDayOfMonth(Date).ToString());
            Result = Year + "/" +   Month   + "/" +   Day  ;   
            return Result;   
        }  

Answer 2

The only reason you get this exception is - item.OrderDate's type not a DateTime. Maby it's string or something else.
