Question

Hi i have mvc web application in which i am stroing courses and students into the table like below

Now in my database table i am saving separate rows for each course & students like student A is having 2 courses and student B is having 1 course as shown above.

Right now My index view is shows three rows what i need to show 2 rows like i need 1 row for each students having comma separated courses below are my model class

public class StudentCoursesViewModel
{
public Moduel Modules { get; set; }
public Years Year { get; set; }
public Student studnets { get; set; }
public Programs programs { get; set; }
public IEnumerable<Courses> curses { get; set; }
public Courses courses { get; set; }
public Student_Assigned_courses studentAssignedCourses { get; set; }
}
}

My controller :

using (DatabaseContext db = new DatabaseContext())
{
List<Student_Assigned_courses> Student_Assigned_courses = db.StudentCoursesAssigned.ToList();
List<Courses> courses = db.Courses.ToList();
List<Moduel> Module = db.Moduels.ToList();
List<Years> year = db.Years.ToList();
List<Programs> Programs = db.Programs.ToList();
List<Student> students = db.Students.ToList();
List<Courses> curr = db.Courses.ToList();
var employeeRecord = from e in Student_Assigned_courses
join d in students on e.Student_id equals d.Student_Id into table1
from d in table1.ToList()
join h in courses on e.Course_Id equals h.Course_Id into table6
from h in table6.ToList()
join i in courses on e.Course_Id equals i.Course_Id into table2
from i in table2.ToList()
join m in Module on e.Module_Id equals m.Id into table3
from m in table3.ToList()
join y in year on e.Year_Id equals y.Id into table4
from y in table4.ToList()
join p in Programs on e.Program_Id equals p.Id into table5
from p in table5.ToList()
select new StudentCoursesViewModel
{
studentAssignedCourses = e,
courses = i,
programs = p,
curses=h,
studnets = d,
Year = y,
Modules = m,
};
return View(employeeRecord);
}

My view:

@model IEnumerable<CMS_Monitoring.ViewModels.StudentCoursesViewModel>
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout2.cshtml";
}
<h2>Index</h2>

@Html.ActionLink("Create New", "Create")
