DropDownListFor selection not being saved - asp.net-mvc

Question

I am new to MVC. I am using a DropDownListFor to display a list of company names and, based on the selection made, filling in other Customer fields. The customer fields are being populated fine, but when I attempt to POST the record, I get a validation error "Company name is required", even though the company name has been selected in the DropDownListFor. Here is the ViewModel:
namespace CMSUsersAndRoles.Models
{
public class QuoteViewModel
{ [Key]
[Display(Name = "Quote Id")]
public int QuoteId { get; set; }
// Columns from Customer table
[Required(ErrorMessage = "Please select a company")]
[Display(Name = "Customer Id")]
public int? CustomerId { get; set; }
[Display(Name = "Sales Rep")]
public string SalesRep { get; set; }
[Display(Name = "First Name")]
public string FirstName { get; set; }
[Display(Name = "Last Name")]
public string LastName { get; set; }
[Required]
public string Company { get; set; }
[Display(Name = "Address 1")]
public string Address1 { get; set; }
[Display(Name = "Address 2")]
public string Address2 { get; set; }
public string City { get; set; }
public string State { get; set; }
[StringLength(10)]
[Display(Name = "Zip Code")]
[RegularExpression(#"^\d{5}(-\d{4})?$", ErrorMessage = "Invalid Zip Code")]
public string PostalCode { get; set; }
[Phone]
[Display(Name = "Work Phone")]
public string WorkPhone { get; set; }
[Phone]
[Display(Name = "Cell Phone")]
public string CellPhone { get; set; }
[EmailAddress]
public string Email { get; set; }
[Range(0, 100)]
public decimal? Discount { get; set; }
[Display(Name = "Payment Terms")]
public int? PaymentTerms { get; set; }
// Columns from QuoteDetail table
[Display(Name = "Quote Detail")]
public List<QuoteDetail> QuoteDetail { get; set; }
// Columns from Quote table
public decimal Subtotal { get; set; }
public decimal Tax { get; set; }
public decimal Total { get; set; }
[DataType(DataType.Date)]
[Display(Name = "Quote Date")]
public DateTime? QuoteDate { get; set; }
[DataType(DataType.Date)]
[Display(Name = "Good Until")]
public DateTime? GoodUntil { get; set; }
[DataType(DataType.Date)]
[Display(Name = "Quote Sent")]
public DateTime? QuoteSent { get; set; }
[DataType(DataType.Date)]
[Display(Name = "Date Approved")]
public DateTime? DateApproved { get; set; }
[DataType(DataType.Date)]
[Display(Name = "Date Ordered")]
public DateTime? DateOrdered { get; set; }
}
}
Here is the code from the View:
#Html.DropDownListFor(model => model.CustomerId, new SelectList(ViewBag.Customers, "CustomerId", "Company"), "---Select one---", new { htmlAttributes = new { #class = "company" } });
#Html.HiddenFor(model => model.Company)
#Html.ValidationMessageFor(model => model.Company, "", new { #class = "text-danger" })
Here is the Get:
public ActionResult Create()
{
QuoteViewModel qvm = new QuoteViewModel();
var customers = db.Customers.ToList();
ViewBag.Customers = customers;
return View(qvm);
}
And here is the code for the POST:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(QuoteViewModel qvm)
{
if (ModelState.IsValid)
{
Quote quote1 = new Quote();
quote1.CustomerId = qvm.CustomerId;
...
customer.CustomerId = (int)qvm.CustomerId;
...
customer.Company = qvm.Company;
db.Entry(customer).State = EntityState.Modified;
try
{
db.SaveChanges();
}
catch (DbUpdateConcurrencyException ex)
{
var objContext = ((IObjectContextAdapter)db).ObjectContext;
// Get failed entry
var entry = ex.Entries.Single();
// Now call refresh on ObjectContext
objContext.Refresh(RefreshMode.ClientWins, entry.Entity);
}
return RedirectToAction("Index");
}
var customers = db.Customers.ToList();
ViewBag.Customers = customers;
return View(qvm);
}
What am I missing? Any help will be much appreciated.

I was not setting the value of the HiddenFor below. Thanks, #StephenMuecke.
#Html.HiddenFor(model => model.Company)
