Grid.MVC giving errors in partial view form

Question

I am trying to use Grid.MVC to pull from my database into a partial view for another view. I have the following in the Empty View I created in the EditorTemplates:

@{
    Layout = null;
}

@using GridMvc.Html
@using Inventory.Entities

@Html.Grid(Model).Columns(columns =>
                    {
                        columns.Add().Encoded(false).Sanitized(false).SetWidth(30).RenderValueAs(o => Html.CheckBox("Checked", false));
                        columns.Add(c => c.ProdName);
                        columns.Add(c => c.ProdID, true);
                    })

I have a Controller and for it that is as follows:

using Inventory.Entities;
using Inventory.Web.DataContext;

namespace Inventory.Web.Controllers
{
    public class ProductionController : Controller
    {
        private CommonDB db = new CommonDB();
                
        // GET: Production
        public ActionResult Production(string prodGrid)
        {
        var ProdList = new List<string>();

            var ProdQry = from p in db.Productions
                          select p.ProdName;
            ProdList.AddRange(ProdQry.Distinct());

            ViewBag.prodGrid = new SelectList(ProdList);

            return View(prodGrid);
        }
    }
}

and the Model is as follows:

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;


namespace Inventory.Entities
    {
    public class Production
        {
        [Key]
        public int ProdID { get; set; }
        [Required]
        public string ProdName { get; set; }

        }
    }

I have used NuGet package manager to add Grid.MVC to the solution, and have added the following to the _Layout.cshtml after the @Scripts.Render("~/bundles/modernizer"):

<script src="@Url.Content("~/Scripts/jquery.min.js")" type="text/javascript"> </script>
    <link href="@Url.Content("~/Content/Gridmvc.css")" rel="stylesheet" type="text/css" />
    <script src="@Url.Content("~/Scripts/gridmvc.min.js")" type="text/javascript"> </script>

I checked and there is a reference to GridMVC in the references, along with all the other files that are needed by it. Unfortunately I am having the following errors thrown: Error 1 The type or namespace name 'GridMvc' could not be found (are you missing a using directive or an assembly reference?)

Error 2 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'Grid' and no extension method 'Grid' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)

I have checked the documentation, and various websites trying to figure out what is wrong, but I am stumped. Does anyone see where I might have done something wrong with this? This is now the holdup with my entire project.

Thank you in advance,

Michael Mastro

Did you check the <pages section in the web.config files inside root and views folders. These should have the namespace liates — Saravanan

It is in the web.config of the root folder. it shows: <pages> <namespaces> <add namespace="GridMvc" /> </namespaces> </pages> — Mike Mastro

I'm guessing one or more js files are not rendering correctly. If you run the page and hit f12, can you verify the the scripts are actually there? — BattlFrog

Try adding

@using NonFactors.Mvc.Grid

statement if your view.

Thanks that was part of the problem. The other part was even though I grabbed the files from NuGet, they were not copied over to the right directory.
