Error: model item passed into the dictionary is of type '....List', but this dictionary requires a model of type '...IEnumerable`

I encountered this error while trying to render an asp.net MVC 3.0 application. I am working with DAB Architecture (3 projects) CAFM.Web, CAFM.Business, and CAFM.Data projects.

CAFM.Data includes

CAFMEntities : Entity FrameWork ITabMaster : Interface namespace CAFM.Data.Interfaces { public interface ITabMaster { TabMaster GetTabMasterById(Int64 id); IEnumerable FindTabMasterByName(string name); void AddTabMaster(TabMaster tabmaster); IEnumerable GetAllTabMaster(); } }

CAFM.Business includes reference of CAFM.Data namespace CAFM.Business.Repositories { public class TabMasterRepository : ITabMaster { public int colID { get; set; } public string FirstName { get; set; } public string LastName { get; set; }

    private CAFMEntities _context;

    public TabMasterRepository()
    {
        //IUnitOfWork unitOfWork = new CAFMEntities();
        _context = new CAFMEntities();
    }

    public TabMasterRepository(IUnitOfWork unitOfWork)
    {
        if (unitOfWork == null)
            throw new ArgumentNullException("unitOfWork");

        _context = unitOfWork as CAFMEntities;
    }

    public IEnumera开发者_运维百科ble<TabMaster> GetAllTabMaster()
    {
        //(extension)List<Movie> IEnumerable<Movie>.ToList<Movie>()
        //List<TabMaster> tabmasters = _context.TabMasters.ToList();
        return _context.TabMasters.ToList() ;// .AsEnumerable<TabMaster>();//.ToList();
        //return tabmasters;
    }

    public TabMaster GetTabMasterById(Int64 id)
    {
        return _context.TabMasters.Where(c => c.colID == id).Single();
    }

    public IEnumerable<TabMaster> FindTabMasterByName(string name)
    {
        return _context.TabMasters.Where(c => c.LastName.StartsWith(name)).AsEnumerable<TabMaster>(); //.ToList();
    }

    public void AddTabMaster(TabMaster tabmaster)
    {
        _context.TabMasters.AddObject(tabmaster);
    }
}

}

CAFM.Web includes reference of CAFM.Data namespace CAFM.Web.Controllers { public class TabMasterController : Controller { // // GET: /TabMaster/

    public ViewResult Index()
    {

        //Error comes in following line. (_context.TabMasters.ToList() is successfully return all the values but error is The model item passed into the dictionary is ... during rendering HTML 
        TabMasterRepository tr = new TabMasterRepository();
        return View(tr.GetAllTabMaster());
    }

}

}

Index.cshtml contains

@model IEnumerable @{ Layout = null; } TabMaster

List of Movies

@Html.ActionLink("Create New", "Create")

ID First Name Last Name @foreach (var item in Model) { @Html.DisplayFor(modelItem => item.colID) @Html.DisplayFor(modelItem => item.FirstName) @Html.DisplayFor(modelItem => item.LastName) }

Error Description: The model item passed into the dictionary is of type 'System.Collections.Generic.List1[CAFM.Data.TabMaster]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[CAFM.Business.Repositories.TabMasterRepository]'.

Please provide your valuable suggestion to resolve above error.

Your answer would be appreciated! Thanks, Imdadhusen

I don't understand why do you want your repository in a view. Did you try to change model to

@model List<CAFM.Data.TabMaster> 

In MVC you should pass data between controller and view thru ViewModels
