我正在尝试制作 MVC WebGrid,我能够让网格正常工作,但面临排序问题。我的rowsPerPage设置为 5,总共有 7 条记录。当我在第一页时,它显示前 5 条记录;当我对 Id 列进行排序时,它会对整个数据进行排序并将第 7 条记录放在顶部。

我的问题 :

  1. 如何使其仅对第一页中存在的元素进行排序并将第 5 条记录放在顶部。
  2. 如何为其创建的数据行添加样式?

代码是这样的: CSHTML -

@model IEnumerable<Product>

@{
    ViewBag.Title = "grid";
    WebGrid grid = new WebGrid(Model, rowsPerPage: 5 );
}

@grid.GetHtml(

    tableStyle: "table",
    fillEmptyRows: true,        
    headerStyle: "main-box-header clearfix",
    footerStyle: "pagination pull-right",

    mode: WebGridPagerModes.All, //paging to grid 
    firstText: "<< First",
    previousText: "< Prev",
    nextText: "Next >",
    lastText: "Last >>",

    columns: new[]  // colums in grid
    {
        grid.Column("Id"), //the model fields to display
        grid.Column("Name"  ),
        grid.Column("Description"),
        grid.Column("Quantity"),

   })

控制器 -

public ActionResult WebgridSample()
        {
            List<Product> inventoryList = new List<Product>();  

            inventoryList.Add(new Product
            {
                Id = "P101",
                Name = "Computer",
                Description = "All type of computers",
                Quantity = 800
            });
            inventoryList.Add(new Product
            {
                Id = "P102",
                Name = "Laptop",
                Description = "All models of Laptops",
                Quantity = 500
            });
            inventoryList.Add(new Product
            {
                Id = "P103",
                Name = "Camera",
                Description = "Hd  cameras",
                Quantity = 300
            });
            inventoryList.Add(new Product
            {
                Id = "P104",
                Name = "Mobile",
                Description = "All Smartphones",
                Quantity = 450
            });
            inventoryList.Add(new Product
            {
                Id = "P105",
                Name = "Notepad",
                Description = "All branded of notepads",
                Quantity = 670
            });
            inventoryList.Add(new Product
            {
                Id = "P106",
                Name = "Harddisk",
                Description = "All type of Harddisk",
                Quantity = 1200
            });
            inventoryList.Add(new Product
            {
                Id = "P107",
                Name = "PenDrive",
                Description = "All type of Pendrive",
                Quantity = 370
            });

            return View(inventoryList);

        }

也许这不是实际的话题,但我会回答实现这件事的最有效方法是进行服务器端排序:

1)在控制器中,您将有 4 个新参数

public ActionResult WebgridSample(int pageNum = 1, int pageSize = 5, string sortColumnName = "",   string sortOrder = "desc")

2) 在您发出 SQL SELECT 请求后,您可以指出您需要从哪个位置检索条目并进行排序(sortOrder = "" 以“按原样”获取列表)

3) 使 Bind() 方法在禁用 autoSortAndPaging 参数的情况下执行,应该指出总条目(之前的构造函数应该知道 rowsPerPage)

4)并且在将所需数据加载到webgrid后不要忘记指向页码

恭喜:)
