I want to print all the dates with column header for the grid view in c#.

//Get current date
            DateTime dt = DateTime.Now; 
            //Get first date
            var startDate = new DateTime(dt.Year, dt.Month, 1);
            //Get tota no of days
            int days = DateTime.DaysInMonth(dt.Year, dt.Month);

            //Loop on days
            for (int i = 0; i < days; i++)
            {        
                dataGridView1.Columns.Add("clm_" + startDate.ToShortDateString(), startDate.ToString("yyyy/MM/dd"));
                startDate= startDate.AddDays(1);
            }
