怎么样在DataGridView里绑定嵌套属性的值？

Question

初学winform 现在用NHibernate从数据库里取出这样两个类的实列：

    public class Achievement
    {
        private long _id;
        private long _studentId;
        private float _makeup2;
        private float _makeup1;
        private float _score;
        private float _credit;
        private string _property;
        private string _className;
        private string _semester;
        private Student _student;

        public virtual long Id
        {
            get { return _id; }
            set { _id = value; }
        }

        public virtual int Version
        {
            get;
            set;
        }

        public virtual string Semester
        {
            get { return _semester; }
            set { _semester = value; }
        }

        public virtual string ClassName
        {
            get { return _className; }
            set { _className = value; }
        }

        public virtual string Property
        {
            get { return _property; }
            set { _property = value; }
        }

        public virtual float Credit
        {
            get { return _credit; }
            set { _credit = value; }
        }

        public virtual float Score
        {
            get { return _score; }
            set { _score = value; }
        }

        public virtual float Makeup1
        {
            get { return _makeup1; }
            set { _makeup1 = value; }
        }

        public virtual float Makeup2
        {
            get { return _makeup2; }
            set { _makeup2 = value; }
        }

        public virtual Student Student
        {
            get { return _student; }
            set { _student = value; }
        }

        public virtual void EditWith(Achievement achievement)
        {
            this.ClassName = achievement.ClassName;
            this.Credit = achievement.Credit;
            this.Makeup1 = achievement.Makeup1;
            this.Makeup2 = achievement.Makeup2;
            this.Property = achievement.Property;
            this.Score = achievement.Score;
            this.Semester = achievement.Semester;
        }
    }

和：

    public class Student
    {
        private long _studentID;
        private string _name;
        private string _major;
        private string _class;
        private string _birthDay;
        private string _pin;
        private string _gender;
        private string _politicalStatue;
        private string _dormitory;
        private string _homeAddress;
        private string _postalCode;
        private string _phone;
        private string _email;
        private string _qq;
        private string _remark;
        private string _ethn;
        private Parent _father;
        private Parent _mother;
        private ISet _achievements = new HashedSet();

        public virtual long StudentId
        {
            get { return _studentID; }
            set { _studentID = value;}
        }

        public virtual int Version { get; set; }

        public virtual string Name

            set { _name = value;}
        }

        public virtual string Major
        {

            set { _major = value;}
        }

        public virtual string Class
        {
            get { return _class; }
            set { _class = value;}
        }

        public virtual string BirthDay
        {
            get { return _birthDay; }
            set { _birthDay = value;}
        }

        public virtual string PIN
        {
            get { return _pin; }
            set { _pin = value;}
        }

        public virtual string Gender
        {
            get { return _gender; }
            set { _gender = value;}
        }

        public virtual string PoliticalStatue
        {
            get { return _politicalStatue; }
            set { _politicalStatue = value;}
        }

        public virtual string Dormitory
        {
            get { return _dormitory; }
            set { _dormitory = value;}
        }

        public virtual string HomeAddress
        {
            get { return _homeAddress; }
            set { _homeAddress = value; }
        }

        public virtual string PostalCode
        {
            get { return _postalCode; }
            set { _postalCode = value; }
        }

        public virtual string Phone
        {
            get { return _phone; }
            set { _phone = value; }
        }

        public virtual string Email
        {
            get { return _email; }
            set { _email = value; }
        }

        public virtual string QQ
        {
            get { return _qq; }
            set { _qq = value; }
        }

        public virtual string Remark
        {
            get { return _remark; }
            set { _remark = value; }
        }

        public virtual string Ethn
        {
            get { return _ethn; }
            set { _ethn = value; }
        }

        public virtual Parent Father
        {
            get { return _father; }
            set { _father = value;}
        }

        public virtual Parent Mother
        {
            get { return _mother; }
            set { _mother = value;}
        }

        public virtual ISet Achievements
        {
            get { return _achievements; }
            set { _achievements = value; }
        }

        public virtual void AddAchievement(Achievement achievement)
        { 
            achievement.Student = this;
            //_achievements.Add(achievement);
            this.Achievements.Add(achievement);
        }

        public virtual bool IsValid()
        {
            if (this._birthDay != string.Empty && this._class != string.Empty && this._dormitory != string.Empty && this._email != string.Empty && this._ethn != string.Empty && this._father != null && this._gender != string.Empty && this._homeAddress != string.Empty && this._major != string.Empty && this._mother != null && this._name != string.Empty && this._phone != string.Empty && this._pin != string.Empty && this._politicalStatue != string.Empty && this._postalCode != string.Empty && this._qq != string.Empty && this._studentID != 0)
            {
                return true;
            }
            return false;
        }

        public virtual int GetTotalCredit()
        {
            if (Achievements == null)
            {
                return 0;
            }
            else
            {
                return (int)Achievements.Cast<Achievement>().Sum(x => x.Credit);
            }
        }

        public virtual void EidtWith(Student stu)
        {
            this.BirthDay = stu.BirthDay;
            this.Class = stu.Class;
            this.Dormitory = stu.Dormitory;
            this.Email = stu.Email;
            this.Ethn = stu.Ethn;
            this.Father.Name = stu.Father.Name;
            this.Father.Phone = stu.Father.Phone;
            this.Gender = stu.Gender;
            this.HomeAddress = stu.HomeAddress;
            this.Major = stu.Major;
            this.Mother.Name = stu.Mother.Name;
            this.Mother.Phone = stu.Mother.Phone;
            this.Name = stu.Name;
            this.Phone = stu.Phone;
            this.PIN = stu.PIN;
            this.PoliticalStatue = stu.PoliticalStatue;
            this.PostalCode = stu.PostalCode;
            this.QQ = stu.QQ;
            this.Remark = stu.Remark;
        }
    }

现在想把一个IList<Achievement>绑定到DataGridView上但在Student属性上出了问题...

如果我想同时显示Student属性的Name怎么办？

是不是为了绑定要从新新建一个包括Student.Name的新对象啊？

希望大家给个思路 谢谢！
