            int inMonth = DateTime.Now.Month;

            //get Day's in current month
            int Days = DateTime.DaysInMonth(DateTime.Now.Year, DateTime.Now.Month);

            //Declare DataTable
            DataTable Dt = new DataTable("dtDays");

            //Declare Data Column
            DataColumn auto = new DataColumn("AutoID", typeof(System.Int32));
            Dt.Columns.Add(auto);

            DataColumn DaysName = new DataColumn("DaysName", typeof(string));
            Dt.Columns.Add(DaysName);

            DataColumn Date = new DataColumn("Date", typeof(string));
            Dt.Columns.Add(Date);

            //Declare Data Row
            DataRow dr = null;
            DateTime days;
            DateTime strDate;

            for (int i = 1; i <= Days; i++)
            {
                //Create row in DataTable
                dr = Dt.NewRow();
                days = new DateTime(Year, inMonth, i);  // find days name
                strDate = new DateTime(Year, inMonth, i); // find date w.r.t days

                dr["AutoID"] = i;
                dr["DaysName"] = days.DayOfWeek;
                dr["Date"] = strDate.Date.ToShortDateString();
                Dt.Rows.Add(dr);    //Add row in DataTable
            }

            //Assign Current Date, Month and Year

            strCurrntMonthYear = DateTime.Now.ToString("dd") + " " + DateTime.Now.ToString("MMMM") + " " + Year;

            //Assing DataTable to GridView
            gvCalander.DataSource = Dt;
            gvCalander.DataBind();
