The Guid Is not passed Correctly in MVC4?

Hi the GUID is not passed correctly.

My Tables

Customer

CustomerID uniqueidentifier primarykey not null,

DisplayName varchar(100)

PrintName varchar(100)

CustomerAddress Table

CustomerAddressID uniqueidentifier primarykey not null,

CustomerID uniqueidentifier null,

AddressID uniqueidentifier null

Address

AddressID uniqueidentifier primarykey not null,

DisplayName varchar(100)

Street varchar(100)

Location varchar(100)

AreaID Uniqueidentifier null,

Pincode varchar(100)

My Model

public class CustomerModel1

{

public System.Guid CustomerID { get; set; }

public string DisplayName { get; set; }

public string PrintName { get; set; }

}

public partial class CustomerAddressModel

{

public System.Guid CustomerAddressID { get; set; }

public Nullable CustomerID { get; set; }

public Nullable AddressID { get; set; }

}

public partial class AddressModel

{

public System.Guid AddressID { get; set; }

public string DisplayName { get; set; }

public string Street { get; set; }

public string Location { get; set; }

public Nullable AreaID { get; set; }

public string PinCode { get; set; }

}

My ViewModel

public class CustomerViewModel

{

public System.Guid CustomerID { get; set; }

public string CustomerName { get; set; }

public System.Guid CustomerAddressID { get; set; }

public System.Guid AddressID { get; set; }

public string Address { get; set; }

public string Street { get; set; }

public string Location { get; set; }

public Nullable AreaID { get; set; }

public string PinCode { get; set; }

}

public class VisitorsEntities1 : DbContext

{

public DbSet Customer { get; set; }

public DbSet CustomerAddress { get; set; }

public DbSet Address { get; set; }

}

My Controller

public ActionResult Create()

{

VisitorsEntities1 db = new VisitorsEntities1();

ViewBag.AreaID = new SelectList(db.Area, "AreaID", "DisplayName", "PrintName");

return View();

}

[HttpPost]

public ActionResult Create(CustomerViewModel viewmodel)

{

ViewBag.AreaID = new SelectList(db.Area, "AreaID", "DisplayName", viewmodel.AreaID);

var Cusobj = Guid.NewGuid();

var CusAddobj = Guid.NewGuid();

var Addobj = Guid.NewGuid();

var Customerobj = new Customer()

{

CustomerID = Cusobj,

DisplayName = viewmodel.CustomerName,

PrintName = viewmodel .CustomerName

};

var CustomerAddressobj = new CustomerAddress()

{

CustomerAddressID = CusAddobj,

CustomerID = viewmodel.CustomerID,

AddressID = viewmodel.AddressID

};

var Addressobj = new Address()

{

AddressID = Addobj,

DisplayName= viewmodel.CustomerName,

Street=viewmodel.Street,

Location= viewmodel.Location,

AreaID = viewmodel.AreaID,

PinCode= viewmodel.PinCode

};

db.Customer.Add(Customerobj);

db .CustomerAddress.Add(CustomerAddressobj );

db.Address.Add(Addressobj);

db.SaveChanges();

return View()

}

Here the AreaID is SubForm So I used ViewBag to bring dropdown in the View and Pass the Guid. Now my issue is with Customer Address Table.

var CustomerAddressobj = new CustomerAddress()

{

CustomerAddressID = CusAddobj,

CustomerID = viewmodel.CustomerID,

AddressID = viewmodel.AddressID

};

Here CustomerAddressID is new Guid is working fine. But

CustomerID = viewmodel.CustomerID,

AddressID = viewmodel.AddressID

The Guid is not passed correctly for this two lines . In table these column is 00000-0000-0000-0000 It didnt show any error and also its not passing the GUID correctly. I donno what the issue is. Please any one help to resolve these problem?

Error

Thanks.

Hi,

reason of error is you are not passing guid from view page. but you are generating in code behind

try this

[HttpPost]
public ActionResult Create(CustomerViewModel viewmodel)
{
ViewBag.AreaID = new SelectList(db.Area, "AreaID", "DisplayName", viewmodel.AreaID);
var CustID = Guid.NewGuid();
var CusAddID = Guid.NewGuid();
var AddID = Guid.NewGuid();
var Customerobj = new Customer()
{
CustomerID = CustID ,
DisplayName = viewmodel.CustomerName,
PrintName = viewmodel .CustomerName
};
var CustomerAddressobj = new CustomerAddress()
{
CustomerAddressID = CusAddID ,
CustomerID = CustID //viewmodel.CustomerID,
AddressID = AddID //viewmodel.AddressID
};
var Addressobj = new Address()
{
AddressID = AddID ,
DisplayName= viewmodel.CustomerName,
Street=viewmodel.Street,
Location= viewmodel.Location,
AreaID = viewmodel.AreaID,
PinCode= viewmodel.PinCode
};
db.SaveChanges();
return View()
}

Instead of var use Guid as datatype like below code:

Guid Cusobj = Guid.NewGuid();
