Kendo UI Grid在初始读取时未显示微调器/加载图标

扎福德

我已经设置了kendo ui网格,以从返回JSON的MVC操作读取数据。由于成本原因,我使用的是Kendo的免费版本,而不是特定的MVC。

问题在于,当页面加载并执行网格的初始填充时,它不会显示加载微调器。填充网格后,我转到另一页或对它显示的列进行排序。

如果设置网格的height参数,则会得到初始微调器,但网格仅显示一行(应该显示20行)。

有谁知道为什么必须设置height参数?或在不设置高度的情况下使微调器工作的任何方式。

我的剑道Javascript Kode:

$("#grid").kendoGrid({
        dataSource: new kendo.data.DataSource({
            transport: {
                read: url,
                parameterMap: function (options) {
                    var result = {
                        pageSize: options.pageSize,
                        skip: options.skip,
                        take: options.take,
                        page: options.page,
                    };

                    if (options.sort) {
                        for (var i = 0; i < options.sort.length; i++) {
                            result["sort[" + i + "].field"] = options.sort[i].field;
                            result["sort[" + i + "].dir"] = options.sort[i].dir;
                        }
                    }

                    return result;
                }
            },
            requestStart: function () {
                //kendo.ui.progress($("#loading"), true); <-- this works on initial load, but gives two spinners on every page or sort change
            },
            requestEnd: function () {
                //kendo.ui.progress($("#loading"), false);

            },
            pageSize: 20,
            serverPaging: true,
            serverSorting: true,
            schema: {
                total: "total", 
                data: "data"
            },
        }),
        height: "100%", <-- I want to avoid this as it renders the grid way to small
        sortable: true,
        pageable: {
            refresh: true,
            pageSizes: true,
            buttonCount: 5
        },
        columns: [
            {
                field: "PaymentRefId",
                title: "Id"
            },
            {
                field: "DueDate",
                title: "Due Date"
            },
            {
                field: "Credit",
                title: "Amount"
            },
            {
                field: "InvoiceGroupId",
                title: " ",
                sortable: false,
                template: '<a href="/InvoiceGroup/InvoiceGroupDetails2/#: InvoiceGroupId #">See details</a>'
            }
        ],
    });

解决方案var使用变量来告诉我数据集负载是否是初始负载。这不是一个完美的解决方案,但它是我唯一能够完成工作的解决方案。

var initialLoad = true;
$("#grid").kendoGrid({
    sortable: true,
    pageable: {
        refresh: true,
        pageSizes: true,
        buttonCount: 5
    },
    columns: [
        {
            field: "PaymentRefId",
            title: "Id"
        },
        {
            field: "DueDate",
            title: "Due Date"
        },
        {
            field: "Credit",
            title: "Amount"
        },
        {
            field: "InvoiceGroupId",
            title: " ",
            sortable: false,
            template: '<a href="/InvoiceGroup/InvoiceGroupDetails2/#: InvoiceGroupId #">See details</a>'
        }
    ],
});
var ds = new kendo.data.DataSource({
        transport: {
            read: url,
            parameterMap: function (options) {
                var result = {
                    pageSize: options.pageSize,
                    skip: options.skip,
                    take: options.take,
                    page: options.page,
                };

                if (options.sort) {
                    for (var i = 0; i < options.sort.length; i++) {
                        result["sort[" + i + "].field"] = options.sort[i].field;
                        result["sort[" + i + "].dir"] = options.sort[i].dir;
                    }
                }

                return result;
            }
        },
        requestStart: function () {
            if (initialLoad) <-- if it's the initial load, manually start the spinner
                kendo.ui.progress($("#invoiceGroupGrid"), true);
        },
        requestEnd: function () {
            if(initialLoad)
                kendo.ui.progress($("#invoiceGroupGrid"), false);
            initialLoad = false; <-- make sure the spinner doesn't fire again (that would produce two spinners instead of one)

        },
        pageSize: 20,
        serverPaging: true,
        serverSorting: true,
        schema: {
            total: "total", 
            data: "data"
        },
    });
