There are a lot of issues with your code. I recommend going through a few beginning level tutorials before moving forward. One of the tutorials on this site has checkbox example (around step 7) similar to your problem statement.
https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/
Below is an example based on your sample.
namespace MvcDemo.Models
{
public class CustomerViewModel
{
public bool Selected { get; set; }
public int ContractId { get; set; }
public Customer Customer { get; set; }
public Decimal TxtPayout { get; set; }
public DateTime TxtDatePaid { get; set; }
}
public class Customer
{
public string Name { get; set; }
}
}
namespace MvcDemo.Controllers
{
public class CustomerController : Controller
{
// GET: Customer
[HttpGet]
public ActionResult Index()
{
List<Models.CustomerViewModel> vm = PopulateViewModel();
return View(vm);
}
[HttpPost]
public ActionResult Update_Record(List<Models.CustomerViewModel> models)
{
List<Models.CustomerViewModel> testData = new List<Models.CustomerViewModel>();
foreach (Models.CustomerViewModel m in models)
{
if(m.Selected)
{
testData.Add(m);
}
}
//Show only the selected records
return View(testData);
}
public List<Models.CustomerViewModel> PopulateViewModel()
{
return new List<Models.CustomerViewModel>()
{
new Models.CustomerViewModel()
{
ContractId = 1,
Customer = new Models.Customer() {Name="Hello"},
TxtDatePaid = DateTime.Now.AddDays(-3),
TxtPayout = 1.01m
},
new Models.CustomerViewModel()
{
ContractId = 2,
Customer = new Models.Customer() {Name="World"},
TxtDatePaid = DateTime.Now.AddDays(-2),
TxtPayout = 1.02m
},
new Models.CustomerViewModel()
{
ContractId = 3,
Customer = new Models.Customer() {Name="Foo"},
TxtDatePaid = DateTime.Now.AddDays(-1),
TxtPayout = 1.03m
},
new Models.CustomerViewModel()
{
ContractId = 4,
Customer = new Models.Customer() {Name="Bar"},
TxtDatePaid = DateTime.Now,
TxtPayout = 1.04m
}
};
}
}
}
