主从 kendo ui 网格（当主网格中的 select 行获取详细信息网格中的条目时）

Question

我正在使用主从 kendo ui 网格，它是分开的。主网格位于选项卡条 1 (tabstrip.select(0)) 内。 add/edit（对于主网格）的字段位于首页的标签条 2 (tabstrip.select(1)) 内。在 tabstrip 2 中，我为详细信息网格嵌套了 tabstrip（在中间底部页面）。详细信息网格位于嵌套标签条 1 (tabstripNested.select(0)) 中，add/edit 的字段位于嵌套标签条 2 (tabstripNested.select(1)) 中。我想要的是？我希望当我 select 主网格中的某行显示详细信息网格中的适当条目时。这是我的主数据源：

var masterDataSource = new kendo.data.DataSource({
    data: [
            { Id: 1, fieldMaster1: "10236", fieldMaster2: "20.01.2015", fieldMaster3: "24.01.2015", fieldMaster4: 1900.0, fieldMaster5: 1900.0, fieldMaster6: 0.0, fieldMaster7: "someth", fieldMaster8: "test" },
            { Id: 2, fieldMaster1: "10648", fieldMaster2: "26.01.2015", fieldMaster3: "28.01.2015", fieldMaster4: 7990.0, fieldMaster5: 7990.0, fieldMaster6: 0.0, fieldMaster7: "skafiskafnjak", fieldMaster8: "test 2" },
            { Id: 3, fieldMaster1: "10700", fieldMaster2: "22.01.2015", fieldMaster3: "25.01.2015", fieldMaster4: 2720.0, fieldMaster5: 2720.0, fieldMaster6: 0.0, fieldMaster7: "temp", fieldMaster8: "test 3" },
            { Id: 4, fieldMaster1: "10810", fieldMaster2: "24.01.2015", fieldMaster3: "27.01.2015", fieldMaster4: 0.0, fieldMaster5: 0.0, fieldMaster6: 0.0, fieldMaster7: "hlabuka", fieldMaster8: "test 4" },
            { Id: 5, fieldMaster1: "10101", fieldMaster2: "29.01.2015", fieldMaster3: "30.01.2015", fieldMaster4: 0.0, fieldMaster5: 0.0, fieldMaster6: 0.0, fieldMaster7: "descr", fieldMaster8: "test 5" },
            { Id: 6, fieldMaster1: "10364", fieldMaster2: "25.01.2015", fieldMaster3: "31.01.2015", fieldMaster4: 0.0, fieldMaster5: 0.0, fieldMaster6: 0.0, fieldMaster7: "TestNova", fieldMaster8: "" }
    ],
    schema: {
        model: {
            id: "Id",
            fields: {
                Id: { type: "number" },
                fieldMaster1: { type: "string" },
                fieldMaster2: { type: "string" },
                fieldMaster3: { type: "string" },
                fieldMaster4: { type: "number" },
                fieldMaster5: { type: "number" },
                fieldMaster6: { type: "number" },
                fieldMaster7: { type: "string" },
                fieldMaster8: { type: "string" }
            }
        }
    }
});

这是我的主网格：

var gridMaster = $("#gridMaster").kendoGrid({
    columns: [
            { field: "Id", hidden: true },
            { field: "fieldMaster1", width: "50px" },
            { field: "fieldMaster2", width: "77px" },
            { field: "fieldMaster3", width: "70px" },
            { field: "fieldMaster4", hidden: true },
            { field: "fieldMaster5", width: "170px" },
            { field: "fieldMaster6", hidden: true },
            { field: "fieldMaster7", width: "80px" },
            { field: "fieldMaster8", width: "80px" }
    ],
    dataSource: masterDataSource,
    selectable:  true,
    filterable: true,
    scrollable: true,
    pageable: {
        pageSize: 16
    },
    toolbar: [{
        name: "create"
    }]
});

这是我的详细信息数据源：

var detailsDataSource = new kendo.data.DataSource({
    data: [
        { Id: 1, masterDataId: 1, fieldDetails1: "20.01.2015", fieldDetails2: "096680", fieldDetails3: "descr1", fieldDetails4: 1000.00, fieldDetails5: 1000.00, fieldDetails6: "ETF", fieldDetails7: "entry1", fieldDetails8: "tmp", fieldDetails9: "20.03.2016", fieldDetails10: "", fieldDetails11: 0.00 },
          { Id: 2, masterDataId: 1, fieldDetails1: "26.01.2015", fieldDetails2: "100258", fieldDetails3: "descr2", fieldDetails4: 900.00, fieldDetails5: 900.00, fieldDetails6: "TMP", fieldDetails7: "entry2", fieldDetails8: "tmp2", fieldDetails9: "20.03.2016", fieldDetails10: "", fieldDetails11: 0.00 },
          { Id: 3, masterDataId: 2, fieldDetails1: "22.01.2015", fieldDetails2: "122554", fieldDetails3: "descr3", fieldDetails4: 970.00, fieldDetails5: 970.00, fieldDetails6: "TMP", fieldDetails7: "entry3", fieldDetails8: "tmp", fieldDetails9: "20.03.2016", fieldDetails10: "", fieldDetails11: 0.00 },
          { Id: 4, masterDataId: 3, fieldDetails1: "24.01.2015", fieldDetails2: "200148", fieldDetails3: "descr4", fieldDetails4: 2000.00, fieldDetails5: 2000.00, fieldDetails6: "ETF", fieldDetails7: "entry1", fieldDetails8: "tmp2", fieldDetails9: "20.03.2016", fieldDetails10: "", fieldDetails11: 0.00 },
          { Id: 5, masterDataId: 2, fieldDetails1: "29.01.2015", fieldDetails2: "344688", fieldDetails3: "descr5", fieldDetails4: 1970.00, fieldDetails5: 1970.00, fieldDetails6: "TMP", fieldDetails7: "entry3", fieldDetails8: "tmp", fieldDetails9: "20.03.2016", fieldDetails10: "", fieldDetails11: 0.00 },
          { Id: 6, masterDataId: 2, fieldDetails1: "25.01.2015", fieldDetails2: "188366", fieldDetails3: "descr", fieldDetails4: 2250.00, fieldDetails5: 2250.00, fieldDetails6: "TMP", fieldDetails7: "entry2", fieldDetails8: "tmp", fieldDetails9: "20.03.2016", fieldDetails10: "", fieldDetails11: 0.00 },
          { Id: 7, masterDataId: 3, fieldDetails1: "24.01.2015", fieldDetails2: "264486", fieldDetails3: "descr1", fieldDetails4: 720.00, fieldDetails5: 720.00, fieldDetails6: "ETF", fieldDetails7: "entry2", fieldDetails8: "tmp", fieldDetails9: "20.03.2016", fieldDetails10: "", fieldDetails11: 0.00 },
          { Id: 8, masterDataId: 2, fieldDetails1: "30.01.2015", fieldDetails2: "400822", fieldDetails3: "descr", fieldDetails4: 2800.00, fieldDetails5: 2800.00, fieldDetails6: "ETF", fieldDetails7: "entry1", fieldDetails8: "tmp2", fieldDetails9: "20.03.2016", fieldDetails10: "", fieldDetails11: 0.00 }
    ],
    schema: {
        model: {
            id: "Id",
            fields: {
                Id: { type: "number" },
                masterDataId: { type: "number" },
                fieldDetails1: { type: "string" },
                fieldDetails2: { type: "string" },
                fieldDetails3: { type: "string" },
                fieldDetails4: { type: "number" },
                fieldDetails5: { type: "number" },
                fieldDetails6: { type: "string" },
                fieldDetails7: { type: "string" },
                fieldDetails8: { type: "string" },
                fieldDetails9: { type: "string" },
                fieldDetails10: { type: "string" },
                fieldDetails11: { type: "number" }
            }
        }
    }
});

这是我的详细信息网格：

var gridDetails = $("#gridDetails").kendoGrid({
    columns: [
      { field: "Id", hidden: true },
      { field: "masterDataId", hidden: true },
      { field: "fieldDetails1", width: "70px" },
      { field: "fieldDetails2", width: "65px" },
      { field: "fieldDetails3", width: "170px" },
      { field: "fieldDetails4", width: "80px" },
      { field: "fieldDetails5", width: "80px" },
      { field: "fieldDetails6", width: "90px" },
      { field: "fieldDetails7", width: "120px" },
      { field: "fieldDetails8", hidden: true },
      { field: "fieldDetails9", hidden: true },
      { field: "fieldDetails10", hidden: true },
      { field: "fieldDetails11", hidden: true }
    ],
    dataSource: detailsDataSource,
    selectable: true,
    filterable: true,
    scrollable: true,
    pageable: {
        pageSize: 10
    },
    toolbar: [{
        name: "create",
        text: "Add New"
    }],
    height: 205
});

detailsDataSource 有masterDataId 字段，与masterDataSource 中的Id 相同。因此，当我 select 主网格中的某行时，我需要从详细信息网格中显示相应的记录。例如：当我 select 主网格中的第一行时，我需要显示详细信息网格中的前两条记录 (masterDataId = 1)。如果我 select 主网格中的第二行，我需要显示详细信息网格中的第三、第五、第六和第八行 (masterDataId = 2)。实现这个的最佳方法是什么？任何帮助表示赞赏。提前谢谢你。

Answer 1

我不确定我是否 100% 正确，但我已经根据你的情况做了一个简单的例子。关键是，当您 change 主网格的选定行时，您必须过滤详细网格，如：

change: function() {
    var gridDetails = $("#grid-detail").data("kendoGrid");
    var dataItem = this.dataItem(this.select());
    gridDetails.dataSource.filter({ field: "parentId", value: dataItem.id, operator: "eq" });
}
