Hi!

I am getting the following error. Can anyone help me solve this error? The code is: -

public class CategoryController : Controller
{
//
// GET: /Category/
ProductsDbEntities ctx;

public CategoryController()
{
ctx = new ProductsDbEntities();
}

public ActionResult Index()
{
try
{
var categoryList = ctx.Categories.ToList();
return View(categoryList);
}

catch (Exception ex)
{
throw ex;
}
}

The code for the View is: -

@model MvcSession.Models.CategoryDetails

@{
ViewBag.Title = "SearchProducts";
}

@using (Html.BeginForm())
{
@Html.EditorFor(cat => cat.CategoryId);

}

I am getting the following error when I run the application :-

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[MvcSession.EntityModel.Category]', but this dictionary requires a model item of type 'MvcSession.Models.CategoryDetails'.

Hi,

I think in the statement

var categoryList = ctx.Categories.ToList();
return View(categoryList);

you are passing List to the view , and in the view you have written

@model MvcSession.Models.CategoryDetails

Probably you should get first or default like following

var selectedCategory= ctx.Categories.FirstOrdefault();

Again you have to map the selected Category with that of MvcSession.Models.CategoryDetails
as following
var categorydetail = new MvcSession.Models.CategoryDetails ();
categoryDetail.property1 = selectedcategory.Property1;
categoryDetail.property2 = selectedcategory.Property2;

Finally

return View(categorydetail );

Hope this will help !!

You define

  @model MvcSession.Models.CategoryDetails

but pass Categories. Modify the above to:

  @model MvcSession.Models.Category
