以下是必须访问嵌套属性的kendo网格：

function detailInit(e) {
    $("<div/>").appendTo(e.detailCell).kendoGrid({
        dataSource: {
            transport: {
                read: constants.AppUrls.GetUrls().WebApi + "gprScoreprofiel/GetProfielen/" + e.data.id
            },
            serverPaging: false,
            serverSorting: false,
            serverFiltering: false,
            sortable: { mode: 'single' },
            pageSize: 5,
            schema: {
                type: "json",
                data: "items",
                model: {
                    fields: {
                        isBerekend: { from: "isBerekend", type: "boolean" },
                        GPR: { from: "gprGebouwVersieId", type: "string" },
                        En: { from: "en", type: "number" },
                        Mi: { from: "mi", type: "number" },
                        Gz: { from: "gz", type: "number" },
                        Gb: { from: "gb", type: "number" },
                        Tk: { from: "tk", type: "number" },
                        Dpg: { from: "dpg", type: "number" },
                        VariantNaam: { from: "variant.naam", type: "string" }

                    }
                }
            }
        },
        dataBound: function (e) {                

        },
        reorderable: true,
        resizable: true,
        sortable: true,
        columnMenu: false,
        scrollable: true, //http://www.telerik.com/forums/max-height-on-grid
        pageable: {
            refresh: true,
            pageSizes: ["All", 10, 20, 50, 100, 200],
            buttonCount: 5,
            messages: {
                display:
                    "{0} - {1} van {2} adressen", //{0} is the index of the first record on the page, {1} - index of the last record on the page, {2} is the total amount of records
                empty: "Geen adressen",
                page: "Page",
                of: "of {0}", //{0} is total amount of pages
                itemsPerPage: "adressen per pagina",
                first: "Ga naar de eerste pagina",
                previous: "Ga naar de vorige pagihna",
                next: "Ga naar de volgende pagina",
                last: "Ga naar de laatste pagina",
                refresh: "Herlaad"
            }
        },
        columns:
        [
            { field: "isBerekend", title: "Berekend", template: "#= isBerekend ? 'Ja' : 'Nee' #" },
            { field: "GPR", title: "GPR versie" },
            { field: "En", title: "Energie" },
            { field: "Mi", title: "Milieu" },
            { field: "Gz", title: "Gezondheid" },
            { field: "Gb", title: "Gebruik" },
            { field: "Tk", title: "Toekomst" },
            { field: "Dpg", title: "Energie en Milieu" },
            { field: "VariantNaam", title: "Variant Naam" }
        ]
    }).data("kendoGrid");
}

在访问api时，我们得到以下数据：

由于variant.naam

，网格不起作用

来自docs：

字段配置不能包含嵌套字段的配置。

所以，你有两个选择：

更改您的API以返回与项目相同级别的嵌套属性，例如：variantnaam;

或者在小部件在schema.parse中呈现它之前在Javascript中执行此操作，例如：

    schema: {
      data: "items",
      parse: function(data) {
        if (data && data.items) {
          var key = "variant";
          data.items.forEach((i) => {
            if (i[key]) {
              Object.keys(i[key]).forEach((k) => {
                i[key + k] = i[key][k];
              });
            }
          });
        }

        return data;
      }
    }
