Kendo UI Grid/Inline 编辑中的“productService”是什么意思

Question

当我阅读代码行时，我正在尝试使用 Kendo UI 创建一个 DataGrid：

private ProductService productService;

    public GridController()
    {
        productService = new ProductService(new SampleEntities());
    }

    protected override void Dispose(bool disposing)
    {
        productService.Dispose();

        base.Dispose(disposing);
    }

我不知道productService 是什么？谁能向我解释它来自哪里以及它在Controller 中是如何工作的？仅供参考link。非常感谢！

不要对此感到困惑……它只是一个示例代码。

对于此示例网格 CustomerViewModel 绑定到网格..

**************网格********

 @(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.CustomerViewModel>()
        .Name("grid")
        .Columns(columns =>
        {
            columns.Bound(c => c.ContactName).Width(140);
            columns.Bound(c => c.ContactTitle).Width(190);
            columns.Bound(c => c.CompanyName);
            columns.Bound(c => c.Country).Width(110);
        })
        .HtmlAttributes(new { style = "height: 380px;" })
        .Scrollable()
        .Groupable()
        .Sortable()
        .Pageable(pageable => pageable
            .Refresh(true)
            .PageSizes(true)
            .ButtonCount(5))
        .DataSource(dataSource => dataSource
            .Ajax()
            .Read(read => read.Action("Customers_Read", "Grid"))
        )
    )

********控制器功能****

public ActionResult Customers_Read([DataSourceRequest]DataSourceRequest request)
        {
            return Json(GetCustomers().ToDataSourceResult(request));
        }

        private static IEnumerable<CustomerViewModel> GetCustomers()
        {
            var northwind = new SampleEntities();
            return northwind.Customers.Select(customer => new CustomerViewModel
            {
                CustomerID = customer.CustomerID,
                CompanyName = customer.CompanyName,
                ContactName = customer.ContactName,
                ContactTitle = customer.ContactTitle,
                Address = customer.Address,
                City = customer.City,
                Region = customer.Region,
                PostalCode = customer.PostalCode,
                Country = customer.Country,
                Phone = customer.Phone,
                Fax = customer.Fax,
                Bool = customer.Bool
            });
        }
