retain values on postback in Asp.net mvc

Question

I have a data in following pattern; as shown in image attached,

I want to repopulate all these values and controls on Postback. I am using asp.net MVC

If i should use a list then how can i tackle the multiple values of subject to be saved in one column but on view displayed in different column

          currently using forms collection:


int rows=request.Form["rows"];
int colmn=requst.form["comn"];


var list1=new list<mymodel>{
new mymodel {}}
;
for (var row = 1; row <= noOfRows; row++)
{

  list1.Add(new mymodel()
   {
       name= Request.Form["name-row"].ConvertToInt()
        rollno= Request.Form["rollno-row"].ToString(),
   });




   for (int colmn = 1; colmn <= noOfColmns - 1; colmn++)
  {
       list1.Add(new mymodel()
      {

          subject = Request.Form["subj-row-colmn"].ConvertToInt()
       });

    }
}

let me know if something else is needed

Important Note:

I think i am not able to explain what i want,so i have narrowed a problem , To be more precise i have created a list ,i have populated a list as

 var list1=new list<mymodel>{
    new mymodel {}}
 list1.Add(new mymodel()
       {
           name= Request.Form["name-row"].ConvertToInt(),
            rollno= Request.Form["rollno-row"].ToString(),
            subj=new list{}

       });

,now i want to loop through this list to get all my values back in the given format. Q:how to get values from this list using loop(foreach or for) in the desired format?

You will need to bind values to a view model, ie, List<MyVM> vm on postback. Then, each view model needs to keep a state for the CRUD. It can be a simple key / value pair, like:

public class MyVM
{
    #region Properties

    #endregion

    public Dictionary<string, VMState> States;
}

public class VMState
{
    public bool Create { get; set; }
    public bool Read { get; set; }
    public bool Update { get; set; }
    public bool Delete { get; set; }
}
