IList does not contain a definition for where, treeview MVC

Question

Hello everyone,

 

In MVC 4, How can I generating a treeview with recursive partial view ?

 

This is the sql database treeview structure.

 

 

 I have tried,

 

namespace Reboxwebapp.Models.ViewModel
{
    public class ProductCategoryVM
    {
        public int idProductCategory { get; set; }
        public string ProductCategoryName { get; set; }
        public string ProductCategoryDescription { get; set; }
        public Nullable<int> idParentCategoryProduct { get; set; }
        public string AlternateNamesToSearch { get; set; }
        public Nullable<int> LevelID { get; set; }
        public string CompletePathName { get; set; }
        public byte[] PCImage { get; set; }

    }

    public class SeededProductCategies
    {
        public int? Seed { get; set; }
        public IList<ProductCategoryVM> Categories { get; set; }
    }
}

[HttpGet]
       public ActionResult GetSearchProduct()
       {
           ProductsBIL objProduct = new ProductsBIL();
           IList<ProductCategoryBL> lsRes = new List<ProductCategoryBL>();
           lsRes = objProduct.GetProductCategoryTree();
           IList<ProductCategoryVM> categories = new List<ProductCategoryVM>();
          // ProductCategoryVM objProductCategoryVM = new ProductCategoryVM();
           // categories = lsRes;
           foreach (var item in lsRes)
           {
               categories.Add(new ProductCategoryVM {idProductCategory =item.idProductCategory,idParentCategoryProduct = item.idParentCategoryProduct,ProductCategoryDescription = item.ProductCategoryDescription });
           }
           SeededProductCategies objSeededProductCategies = new SeededProductCategies { Seed = null, Categories = categories };
           return View(objSeededProductCategies);
       }

  GetSearchProduct actionresult go to view is shown below, 

@model Reboxwebapp.Models.ViewModel.SeededProductCategies


@Html.Partial("_TreeCategories", Model)

 then partial view, 

@model Reboxwebapp.Models.ViewModel.SeededProductCategies

@if (Model.Categories.Where(s => s.idParentCategoryProduct == Model.Seed).Any()) /*But here is occurring error : ilist does not contain a definition for where cause*/
{
    <ul>
        @foreach (var node in Model.Categories)
        {
            if (node.idParentCategoryProduct == Model.Seed)
            {
                Reboxwebapp.Models.ViewModel.SeededProductCategies inner = new Reboxwebapp.Models.ViewModel.SeededProductCategies { Seed = node.idProductCategory, Categories = Model.Categories };
                <li>
                    <a href="[email protected]">@node.ProductCategoryDescription</a>
                    @Html.Partial("_TreeCategories", inner)
                </li>
            }
        }
    </ul>
}

 How can I do this? Please help me.
