nopcommerce オープン ソースを使用しています。そのため、別のテーブルを追加し、Product Variant に別のタブを追加したいと考えています。

だから私はモデルを作成します。

 public partial class ProductVariantPriceRangeModel : BaseNopEntityModel
        {
            public int ProductVariantId { get; set; }

             [NopResourceDisplayName("Admin.Catalog.Products.Variants.ProductVariantPriceRange.Fields.SpecialPriceStartDate")]
           [DisplayFormat(NullDisplayText = "", DataFormatString = "{0:yyyy-MM-dd}")]

            public DateTime? SpecialPriceStartDate { get; set; }

             [NopResourceDisplayName("Admin.Catalog.Products.Variants.ProductVariantPriceRange.Fields.SpecialPriceEndtDate")]
            [DisplayFormat(NullDisplayText = "", DataFormatString = "{0:yyyy-MM-dd}")]

            public DateTime? SpecialPriceEndtDate { get; set; }


            [NopResourceDisplayName("Admin.Catalog.Products.Variants.ProductVariantPriceRange.Fields.Price")]

            public decimal Price1 { get; set; }
        }

これが私のコントローラーです。

[HttpPost, GridAction(EnableCustomBinding = true)]
        public ActionResult ProductVariantPriceRangeList(GridCommand command, int productVariantId)
        {
            if (!_permissionService.Authorize(StandardPermissionProvider.ManageCatalog))
                return AccessDeniedView();

            var productVariant = _productService.GetProductVariantById(productVariantId);
            if (productVariant == null)
                throw new ArgumentException("No product variant found with the specified id");

            var productVariantPriceRange = productVariant.ProductVariantPriceRange;
            var productVariantPriceRangeModel = productVariantPriceRange
                .Select(x =>
                {
                    return new ProductVariantModel.ProductVariantPriceRangeModel()
                    {                      

                        Id = x.Id,                       
                        ProductVariantId = x.ProductVariantId,
                        SpecialPriceStartDate = x.SpecialPriceStartDate,
                        SpecialPriceEndtDate=x.SpecialPriceEndtDate,                       
                        Price1 = x.SpecialPrice
                    };
                })
                .ToList();

            var model = new GridModel<ProductVariantModel.ProductVariantPriceRangeModel>
            {
                Data = productVariantPriceRangeModel,
                Total = productVariantPriceRangeModel.Count
            };

            return new JsonResult
            {
                Data = model
            };
        }

これが私の見解です。

@model ProductVariantModel
@using Telerik.Web.Mvc.UI;

@using Nop.Admin;

@Html.HiddenFor(model => model.Id)

@Html.Telerik().TabStrip().Name("productvariant-edit").Items(x =>
{
    x.Add().Text(T("Admin.Catalog.Products.Variants.Info").Text).Content(TabInfo().ToHtmlString()).Selected(true);
    x.Add().Text(T("Admin.Catalog.Products.Variants.TierPrices").Text).Content(TabTierPrices().ToHtmlString());
     x.Add().Text(T("Admin.Catalog.Products.Variants.ProductVariantAttributes").Text).Content(TabProductVariantAttributes().ToHtmlString());
    x.Add().Text(T("Admin.Catalog.Products.Variants.Discounts").Text).Content(TabDiscounts().ToHtmlString());

    x.Add().Text(T("Admin.Catalog.Products.Variants.ProductVariantPriceRange").Text).Content(TabProductVariantPriceRange().ToHtmlString());

    //generate an event
    EngineContext.Current.Resolve<IEventPublisher>().Publish(new AdminTabStripCreated(x, "productvariant-edit"));
})



@helper TabProductVariantPriceRange()
    {
      if (Model.Id > 0)
        {

                    keys.Add(x => x.Id);
                })
                .DataBinding(dataBinding =>
                {
                    dataBinding.Ajax()
                        .Select("ProductVariantPriceRangeList", "ProductVariant", new { productVariantId = Model.Id })
                        .Insert("ProductVariantPriceRangeInsert", "ProductVariant", new { productVariantId = Model.Id })

                })
                .Columns(columns =>
                {
                    columns.Bound(x => x.ProductVariantId)
                        .Width(100).ReadOnly()
                        .Centered();                    


                    columns.Bound(x => x.SpecialPriceStartDate)

                    columns.Bound(x => x.Price1)
                        .Width(100);
                    columns.Command(commands =>
                    {
                        commands.Edit();
                        commands.Delete();
                    })
                    .Width(180);


                })
                .ToolBar(commands => commands.Insert())
                .ClientEvents(events => events.OnEdit("onTierPriceEdit"))
                .EnableCustomBinding(true))


        }
        else
        {
    @T("Admin.Catalog.Products.Variants.ProductVariantPriceRange.SaveBeforeEdit")
        }

}
