asp.net-mvc - MVCGrid.net - 网格不分页结果，也显示所有记录和寻呼机

Question

正在显示启用了分页器但显示所有记录而不分页的网格。也显示寻呼机。RegisterGrid() 方法的代码如下：-

public static void RegisterGrids()
        {
            GridDefaults defaultSet1 = new GridDefaults()
            {
                Paging = true,
                ItemsPerPage = 5,
                NoResultsMessage = "Sorry, no results were found"
            };

            MVCGridDefinitionTable.Add("grdFiles", new MVCGridBuilder<FilesModel>(defaultSet1)
            .WithAuthorizationType(AuthorizationType.AllowAnonymous)
            .AddColumns(cols =>
            {
                cols.Add("FileName")
                    .WithValueExpression(p => p.Name.ToString());
                cols.Add("LastModified").WithHeaderText("LastModified")
                    .WithValueExpression(p => p.LastModified.ToString());
                cols.Add("Size").WithHeaderText("Size")
                    .WithValueExpression(p => p.Size.ToString());
            })
            .WithRetrieveDataMethod((context) =>
            {
                var res = DisplayFiles();
                return new QueryResult<FilesModel>()
                {
                    Items = res,
                    TotalRecords = res.Count // if paging is enabled, return the total number of records of all pages
                };
            })
            );
        }

查看代码是：

@model IEnumerable<FileViewerWeb.Models.FilesModel>

@using MVCGrid.Web;

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
<div class="well well-lg" style="padding-top:10px">
    <h2>Explore Uploaded Files</h2>
</div>

@Html.MVCGrid("grdFiles")

控制器代码：-

public ActionResult Index()
{
return View();
}

Answer 1

当你使用 skip 时，你必须首先使用 orderby。

if (options.GetLimitOffset().HasValue)
{
    var limitOffset = options.GetLimitOffset().Value;
    var limitRowCount = options.GetLimitRowcount().Value;
    query = query.OrderBy(c=>c.name) //or add any column you prefer to order the list
        .Skip(limitOffset)
        .Take(limitRowCount);
}

Answer 2

将生成列表的方式更改为查询，然后最后通过ToList()

var result = new QueryResult<FilesModel>();
var query = db.FilesModel.AsQueryable();

您缺少代码

if (options.GetLimitOffset().HasValue)
{
    var limitOffset = options.GetLimitOffset().Value;
    var limitRowCount = options.GetLimitRowcount().Value;
    query = query
        .Skip(limitOffset)
        .Take(limitRowCount);
}

最后，在返回使用点

result.Items = query.ToList();
result.TotalRecords = result.Items.Count();
return result;
