try this,

C#

private void DGVCalendar_CurrentCellDirtyStateChanged(object sender, EventArgs e)
        {
            try
            {


                DataGridView dgv = (DataGridView)sender;
                DataGridViewCell cell = dgv.CurrentCell;
                if (cell.RowIndex > -1 && (cell.ColumnIndex == 1 || cell.ColumnIndex == 2))
                {
                    if (cell.ColumnIndex == 1)
                    {
                        DGVCalendar.Rows[cell.RowIndex].Cells[1].Value = true;
                        DGVCalendar.Rows[cell.RowIndex].Cells[2].Value = false;
                    }
                    else
                    {
                        DGVCalendar.Rows[cell.RowIndex].Cells[2].Value = true;
                        DGVCalendar.Rows[cell.RowIndex].Cells[1].Value = false;                    
                    }
