How to display a list using ViewBag

Question

Hi i need to show a list of data using viewbag.but i am not able to do it.
Please Help me..
I tried this thing:

 ICollection<Learner> list = new HobbyHomeService().FetchLearner();
 ICollection<Person> personlist = new HobbyHomeService().FetchPerson(list);
 ViewBag.data = personlist;

and inside view:

 <td>@ViewBag.data.First().FirstName</td>

But this does not show up the value and gives error saying "Model.Person doesnot contain a defibition for First()"

In your view, you have to cast it back to the original type. Without the cast, it's just an object.

<td>@((ViewBag.data as ICollection<Person>).First().FirstName)</td>

ViewBag is a C# 4 dynamic type. Entities returned from it are also dynamic unless cast. However, extension methods like .First() and all the other Linq ones do not work with dynamics.

Edit - to address the comment:

If you want to display the whole list, it's as simple as this:

<ul>
    @foreach (var person in ViewBag.data)
    {
        <li>@person.FirstName</li>
    }
</ul>

Extension methods like .First() won't work, but this will.

hey thanx i got the value but can u tell me how can i fetch all the values assigned in the list? — user1274646, May 09 '12 at 19:00

To put it all together, this is what it should look like:

In the controller:

List<Fund> fundList = db.Funds.ToList();
ViewBag.Funds = fundList;

Then in the view:

@foreach (var item in ViewBag.Funds)
{
    <span> @item.FundName </span>
}

Great Chris. I liked your approach, but that is not what I am looking for. Even then, one up-vote for you for your nice approach. – Ashok kumar Jul 29 '20 at 09:10

simply using Viewbag data as IEnumerable<> list

@{
 var getlist= ViewBag.Listdata as IEnumerable<myproject.models.listmodel>;

  foreach (var item in getlist){   //using foreach
<span>item .name</span>
}

}

//---------or just write name inside the getlist
<span>getlist[0].name</span>

i had the same problem and i search and search .. but got no result.
so i put my brain in over drive. and i came up with the below solution. try this in the View Page

at the head of the page add this code

 @{
      var Lst = ViewBag.data as IEnumerable<MyProject.Models.Person>;
    }

to display the particular attribute use the below code

@Lst.FirstOrDefault().FirstName

in your case use below code.

<td>@Lst.FirstOrDefault().FirstName </td>

Hope this helps...

Use as variable to cast the Viewbag data to your desired class in view.

@{

IEnumerable<WebApplication1.Models.Person> personlist = ViewBag.data as
IEnumerable<WebApplication1.Models.Person>;
// You may need to write WebApplication.Models.Person where WebApplication.Models is
  the namespace name where the Person class is defined. It is required so that view 
  can know about the class Person. 
}

In view write this

<td>
    @(personlist.FirstOrDefault().Name)
</td>

 List<Person>

into the ViewBag and in the View cast it back to List

    public ActionResult Index()
    {
      List<Fund> fundList = db.Funds.ToList();
     ViewBag.Funds = fundList;
        return View();
    }

I had the problem that I wanted to use my ViewBag to send a list of elements through a RenderPartial as the object, and to this you have to do the cast first, I had to cast the ViewBag in the controller and in the View too.

In the Controller:

ViewBag.visitList = (List<CLIENTES_VIP_DB.VISITAS.VISITA>)                                                                 
visitaRepo.ObtenerLista().Where(m => m.Id_Contacto == id).ToList()

In the View:

List<CLIENTES_VIP_DB.VISITAS.VISITA> VisitaList = (List<CLIENTES_VIP_DB.VISITAS.VISITA>)ViewBag.visitList ;
