Method 1

You can use string to display it :

[DataType(DataType.Date)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public string MyDate { get; set; }

You can convert DateTime to string using Book’s class constructor :

     public Book()
      {
        this.MyDate = Mydate.ToString();
      }

I would also change DateAndTime to DateTime as long as you declare using c# :

    public DateTime Mydate = DateTime.Now;

OR

What I would do is reducing amount of properties. If I understand correctly what you want to achive, this should be enough :

        public class Book
        {
            [Key]
            public int PO { get; set; }
            [Required]
            public string Creator { get; set; }
            [Required]
            public string Company { get; set; }
            [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
            public string MyDate { get { return DateTime.Now.ToString(); } set { } }

        }
