Use variable from controller in view ASP.NET MVC4 - asp.net

Question

There is a model in my project
using System;
namespace Argussite.SupplierServices.ViewModels
{
public class UsersPage
{
public Guid SupplierId { get; set; }
public string SupplierFullName { get; set; }
public bool ActionsAllowed { get; set; }
}
}
I use my model in controller and set properties
public ActionResult Index(Guid id)
{
var supplierOfUser = Context.Suppliers.AsNoTracking()
//.Include(e => e.Supplier)
.FirstOrDefault(e => e.Id == id);
string SupplierId = id.ToString();
string SupplierFullName = supplierOfUser.FullName.ToString();
bool ActionsAllowed = supplierOfUser.Active;
return View();
}
and then I need to use that in view, but I don't know how to get my properties in the view?

Answer 1

Firstly your controller action needs to send that model instance to the view like this:
return View(supplierOfUser);
You need this at the top of your view:
#model Argussite.SupplierServices.ViewModels.UsersPage
Then all you need to do is whereever you want to use your model in the view do:
#Model.SupplierFullName
If you want to use other properties in the view that you can place them into a dynamic ViewBag variable like this:
ViewBag.supplierOfUser = supplierOfUser.FullName.ToString();
and then on your view you can use this value like this:
#ViewBag.supplierOfUser

Answer 2

Create a new UsersPage and assign the properties you already have to its properties, then pass the newly created UsersPage to the view:
public ActionResult Index(Guid id)
{
var supplierOfUser = Context.Suppliers.AsNoTracking()
//.Include(e => e.Supplier)
.FirstOrDefault(e => e.Id == id);
var usersPage = new UsersPage();
usersPage.SupplierId = id.ToString();
usersPage.SupplierFullName = supplierOfUser.FullName.ToString();
usersPage.ActionsAllowed = supplierOfUser.Active;
return View(usersPage);
}

Answer 3

In order to use your data from the controller to the view, you need to return the view with your model in parameter:
return View(supplierOfUser);
In your view, you'd also need to define the model:
#model YourModel
Note that you don't need to set your supplier info into other variables (only supplierOfUser is required).

Answer 4

Best way is to establish a strongly typed model in the view:
#model Argussite.SupplierServices.ViewModels.UsersPage
Then, just reference the properties on the model, e.g.
#Html.EditorFor(model => model.SupplierFullName)

Answer 5

It's hard to help you with exact code as I don't know what you want to do on your view, this is a general idea of how you're supposed to pass and use your model in your view
Controller
public ActionResult Index(Guid id)
{
var supplierOfUser = Context.Suppliers.AsNoTracking()
.FirstOrDefault(e => e.Id == id);
var usersPage = new UsersPage
{
SupplierId = supplierOfUser.Id,
SupplierFullName = supplierOfUser.FullName,
ActionsAllowed = supplierOfUser.Active
}
return View(usersPage ); // <-- Send viewmodel to view
}
VIEW
// Declare model
#model Argussite.SupplierServices.ViewModels.UsersPage
...
//Use your model here at will
#Html.DisplayFor(modelItem => item.FullName)
...
#Html.EditorFor(model => model.FullName)
#Html.ValidationMessageFor(model => model.FullName)
