导读：我正在使用类似于 here提到的webgrid @{ var grid = new WebGrid(canPage: true,rowsPerPage: ThisController.PageSize,canSort: true,ajaxUpdateContainerId: "grid"); grid.Bind(Model.Employees,rowCount: Model.TotalRecords,autoSortAndPage: false); g

我正在使用类似于 here提到的webgrid

@{
    var grid = new WebGrid(canPage: true,rowsPerPage: ThisController.PageSize,canSort: true,ajaxUpdateContainerId: "grid");
    grid.Bind(Model.Employees,rowCount: Model.TotalRecords,autoSortAndPage: false);
    grid.Pager(WebGridPagerModes.All);
    @grid.GetHtml(htmlAttributes: new { id="grid" },columns: grid.Columns(
            grid.Column(format: (item) => Html.ActionLink("Edit","Edit",new { EmployeeID = item.EmployeeID })),grid.Column("FullName"),grid.Column("Title")
        ));
}

但在我的情况下,我期待超过2000条记录,我想加载每页只加载50条记录,以便页面加载速度更快.如何确保在加载页面时仅加载前50条记录.当我的用户单击page2时,我想加载下一组50条记录,依此类推.
你们中的任何人都遇到过类似的问题,请给我一些示例代码

解决方法

这篇MSDN杂志文章展示了你想要的东西：

Get the Most out of WebGrid in ASP.NET MVC

阅读本节：添加分页和排序

As you can see,the data we’re passing contains the full list of products (295 of them in this example,but it’s not hard to imagine scenarios with even more data being retrieved). As the amount of data returned increases,you place more and more load on your services and databases,while still rendering the same single page of data. But there’s a better approach: server-side paging. In this case,you pull back only the data needed to display the current page (for instance,only five rows).
