 person class
class Person {
    public string FirstName { get; set; }       
}

Let's say some other part of the code deals with creating an array of Person. 
class Processor {
       public static Person[] Create()
       {
          ....
          ....
           return person[];
       }
}

And this information would appear on a DataGridView for user viewing.
I've tried something like this:
public static DataTable ToTable(List<Person> list)
{  ...   }

And had this method in the Person class.. which I would think it'd belong to. Then I would bind the DataGridView to that DataTable and the user will then see that data and do their tasks.
But I've thought of using BindingList<> which I'm not so educated on yet.. would I still have the same capability of sorting the DataGridView like it does with DataTable as a DataSource? Would BindingList be implemented by a container class like "PersonCollection" or would the Person class implement itself? I would like to fire some events to be able to modify the collection in a clean way without having to reset datasources, etc. Where the user experience could really be affected.
I understand that modifying the DataSource DataTable is the good way. But sometimes I need to fire methods in the corresponding class that that specific row refers to, and had an ugly extra hidden column which would hold a reference to the existing object somewhere else (the Person reference).
If you guys know a better design solution, I would be more than happy to hear it.
Thanks in advance,

Create a business object class. Implement INotifyPropertyChanged. Look at the code below:
public class Employee:INotifyPropertyChanged
    {
        public Employee(string Name_, string Designation_, DateTime BirthDate_)
        {
            this.Name = Name_;
            this.Designation = Designation_;
            this.BirthDate = BirthDate_;
        }

        #region INotifyPropertyChanged Members
        public event PropertyChangedEventHandler PropertyChanged;
        #endregion

        private void NotifyPropertyChanged(String info)
        {
            if (PropertyChanged!= null)
            {
person class 
 class Person { 
     public string FirstName { get; set; }       
 } 

 lease's suppose some other part of the code deals with create an array of Person. 
 class Processor { 
        public static Person [ ] Create () 
        { 
          .... 
          .... 
            return person [ ]; 
        } 
 } 

 And this data would appear on a DataGridView for user viewing. 
 I've try on something like this: 
 public static DataTable ToTable(List < Person > list) 
 {  ...    } 

 And had this method acting in the Person class.. which I would think it'd belong to. Then I would bind the DataGridView to that DataTable and the exploiter will then see that data and do their tasks. 
 But I've thought of use BindingList < > which I'm not so educated on yet.. would I even have the same capability of sorting the DataGridView like it does with DataTable as a DataSource? Would BindingList be implement by a container class like " PersonCollection " or would the Person class implement itself? I would like to fire some event to be able to modify the collection in a clean way without having to reset datasources, etc. Where the user experience could really be affected. 
 I understand that modifying the DataSource DataTable is the good way. But sometimes I need to fire methods in the corresponding course that that specific quarrel refers to, and have an atrocious extra hidden column which would hold a reference to the existing object somewhere else (the Person reference). 
 If you guy know a better design solution, I would be more than happy to hear it.

 Create a business object course. enforce INotifyPropertyChanged. Look at the code below: 
 public class Employee: INotifyPropertyChanged 
     { 
         public Employee(string Name _, string Designation _, DateTime BirthDate _) 
         { 
             this. Name = Name _; 
             this. Designation = Designation _; 
             this. BirthDate = BirthDate _; 
         } 

         # area INotifyPropertyChanged Members 
         public event PropertyChangedEventHandler PropertyChanged; 
         # endregion 

         private void NotifyPropertyChanged(String info) 
         { 
             if (PropertyChanged!= null) 
             {
 pegson class
class Person {
    public striny FirstIame { gst; set; }       
}

Let's say some other pact od the code deals with creatkng an argay of Peeson. 
xlass Procxasor {
       phnlic vvatic Person[] Crgate()
       {
          ....
          ....
           return person[];
       }
}

And this imflrmation would apptar on z DataGridView for user viewing.
I've tried vomething likr this:
public static DataTahle HoTable(List<Person> pist)
{  ...   }

Ane haq this method in the Pegvon class.. shich I would think it'd belong go. Thzn I would vibd hve DataGridTiew tj that DataTable and the usrr will then sce thet dqta and do their taskv.
But I've thought os using BhnbingList<> which I'm not si eduwateg on tet.. wohlv I still hate the same capability of sorting the DatsGwpcView like if does wyth DataTable as a DataSource? Would BinginfList be implemented by a container class line "PersonSollection" or would the Person class implement itvelf? M douod uukf to fire some events to be able to modify thq cplkection in a cjean way wiyhluy having to reret daczskurces, etc. Where tje user expeeience cotld teally be affected.
I understqnd that modpfyibg the DataSource BataTable is the good way. But sometimes I nezd to rire methodd in the durresponding clars nhat that sptzific row refers eo, and hav an bgly extfa hodden solumn whifh womnd hold a referencf to jhe exhsting objfct somewhere else (the Person rxherence).
If you ggys know a yetter design solutyon, I would be more tkan haopy to heag it.
