Hi akhter,
Use DropDownListFor.
Check this example. Now please take its reference and correct your code.
Database
For this example I have used of Northwind database that you can download using the link given below.
Download Northwind Database
Model
public class tbl_Student
{
public string std_id { get; set; }
public string std_Name { get; set; }
public List<SelectListItem> ClassList { get; set; }
public string ClassId { get; set; }
}
Controller
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
tbl_Student student = new tbl_Student();
student.ClassList = GetClasss();
ViewBag.saveresult = "";
return View(student);
}
[HttpPost]
public ActionResult Index(tbl_Student student)
{
using (NorthwindEntities entities = new NorthwindEntities())
{
Customer s = new Customer();
s.CustomerID = student.std_id;
s.ContactName = student.std_Name;
entities.Customers.Add(s);
entities.SaveChanges();
ViewBag.saveresult = "Data Save";
ModelState.Clear();
}
return View(new tbl_Student() { ClassList = GetClasss() });
}
private static List<SelectListItem> GetClasss()
{
NorthwindEntities entities = new NorthwindEntities();
List<SelectListItem> classList = (from p in entities.Customers
select new SelectListItem
{
Text = p.ContactName,
Value = p.CustomerID.ToString()
}).ToList();
//Add Default Item at First Position.
classList.Insert(0, new SelectListItem { Text = "--Select Class--", Value = "" });
return classList;
}
}
