POST a form array without successful

Question

I\'m developing an ASP.NET MVC 5 web with C# and .NET Framework 4.5.1.

I have this form in a cshtml file:

@model MyProduct.

you can visit this article for complete source code with a video tutorial.

you have to create an action first, from where we can pass the list of object

[HttpGet]
public ActionResult Index()
{
    List model = new List();
    using (MyDatabaseEntities dc = new MyDatabaseEntities())
    {
        model = dc.Contacts.ToList();
    }
    return View(model);
}

then we need to create a view for that action

@model List
@{
    ViewBag.Title = "Update multiple row at once Using MVC 4 and EF ";
}
@using (@Html.BeginForm("Index","Home", FormMethod.Post))
{
    
        @for (int i = 0; i < Model.Count; i++)
        {
            
        }
    

            

                
               
                
Contact Person
                
Contact No
                
Email ID
            
               
                
 @Html.HiddenFor(model => model[i].ContactID)
                
@Html.EditorFor(model => model[i].ContactPerson)
                
@Html.EditorFor(model => model[i].Contactno)
                
@Html.EditorFor(model => model[i].EmailID)
            
    

    

        @ViewBag.Message
    
}
 @section Scripts{
    @Scripts.Render("~/bundles/jqueryval")
 }

and then we have to write code for save the list of object to the database

[HttpPost]
public ActionResult Index(List list)
{  
    if (ModelState.IsValid)
    {
        using (MyDatabaseEntities dc = new MyDatabaseEntities())
        {
            foreach (var i in list)
            {
                var c = dc.Contacts.Where(a =>a.ContactID.Equals(i.ContactID)).FirstOrDefault();
                if (c != null)
                {
                    c.ContactPerson = i.ContactPerson;
                    c.Contactno = i.Contactno;
                    c.EmailID = i.EmailID;
                }
            }
            dc.SaveChanges();
        }
        ViewBag.Message = "Successfully Updated.";
        return View(list);
    }
    else
    {
        ViewBag.Message = "Failed ! Please try again.";
        return View(list);
    }
}
