Question

我有一个包含165个元素的数据数组，我在OnDemandGrid中显示它们，按日期字段排序。但是，当网格显示时，仅显示数据数组中的 last 140元素（即具有最近140个日期的元素）。但是，如果我单击日期标题以反转排序，则第一个 140元素显示（即具有最早的140个日期的元素）。所以我的猜测是，不知何故延迟加载的机制不起作用，我仍然不明白为什么只显示数组的最后部分而不是第一部分。我没有使用分页，也没有设置与大小相关的其他选项。有什么建议吗？

网格将添加到页面中已有的div中：

<div id="navList" class="dgrid-autoheight"></div>

这里是网格的代码，下面你可以找到数据数组：

function fillNavList(data) {
    var columns =
    [
        {
            field : "date",
            label : L["date"]
        },
        {
            field : "value",
            label : L["value"]
        },
        {
            field : "dateModification",
            label : L["dateModification"]
        },
        {
            field : "status",
            label : L["status"]
        },
        {
            field : "valueRefId",
            label : L["valueRefId"]
        }
    ];
    require(
    [
        "dojo/on",
        "dstore/Memory",
        "dstore/Filter",
        "dgrid/OnDemandGrid",
        "dojo/_base/declare"
    ], function(on, Memory, Filter, OnDemandGrid, declare) {

    var store = new Memory({
        data : data
    });
    var navList = new (declare(
        [
            OnDemandGrid
        ]))({
        columns : columns,
        sort: "date",
        collection : store,
        addUiClasses : false
    }, "navList");

    });
}

以下是数据：
