如何在层次网格中过滤嵌套 Kendo UI 数据源的数据

Question

如何过滤层次网格中嵌套 Kendo UI 数据源的数据 以下是数据源：

Obj1{"Name":"abc","id":1 ,Obj2 {{"Name":"A1","oid":1},{"Name":"A2","oid":2}}

我需要搜索出现在详细网格中的 Obj2 名称。 请帮忙。

Answer 1

使用您的数据准备 viewModel 和数据源

$(document).ready(function () {
var viewModel = kendo.observable({
    //here define a datasource - i followed your data with improv
    datasource: new kendo.data.DataSource({
        data: [{
            name: 'abc',
            id: 1,
            obj2: [{
                name: 'a1',
                oid: 1
            }, {
                name: 'b1',
                oid: 2
            }, {
                name: 'c1',
                oid: 3
            }]
        }, {
            name: 'def',
            id: 4,
            obj2: [{
                name: 'd1',
                oid: 4
            }, {
                name: 'e1',
                oid: 5
            }]
        }, {
            name: 'ghi',
            id: 3,
            obj2: [{
                name: 'g1',
                oid: 6
            }, {
                name: 'h1',
                oid: 7
            }]
        }]
    }),
    //define the function when we want to click the expand button
    detail: function (e) {
        //bind it now
        kendo.bind(e.detailCell, e.data);
    }
});

//1 st bind container with the kendo observable
kendo.bind('#container', viewModel);

//grab the grid and bind its 'detailInit' event with our 'detail' function
var grid = $('#grid').getKendoGrid();
grid.bind('detailInit', viewModel.detail);

});

并准备 html 网格和详细网格的模板

<div id="container">
    <br/>
    <br/>
    <div id="grid" data-role="grid" data-bind="source: datasource" data-detail-template="child-template" data-columns="[
            { field: 'name' },
            { field: 'id' },
        ]"></div>
</div>
<script id="child-template" type="text/x-kendo-template">
    <div data-role = "grid"
    data-bind = "source: obj2"
    data-columns = "[
    { field: 'name' },
    { field: 'oid' }
    ]"> </div>
</script>

最后这是jsfiddle，这个tutorial教我怎么做

编辑：我在每个详细信息网格顶部添加了一个下拉列表，因此您可以从那里过滤它们，这是jsfiddle

Answer 2

我遇到了同样的问题，无法在子网格中应用过滤器。

解决方法如下：

我的html代码：

            <div class="panel-body custom-table" id="divAllCall">
                <div class="row">
                    <div class="col-md-12">
                        @(Html.Kendo().Grid<FW.Model.model>()
                        .Name("gridTest")
        .Columns(col =>
        {
            col.Bound(c => c.Id).Hidden(true);
            col.Bound(c => c.Name).Title("Name").HeaderHtmlAttributes(new { title = "Port" }).Width(100);
            col.Bound(c => c.col1).Title("col1").HeaderHtmlAttributes(new { title = "Upcoming Calls" }).Width(100);
            col.Bound(c => c.col2).Title("col2").HeaderHtmlAttributes(new { title = "Calls In Port" }).Width(100);


        })
        .Sortable()
        .Scrollable()
        .HtmlAttributes(new { style = "height: 380px" })
        .Pageable(pageable => pageable.Refresh(true)
        .PageSizes(new int[5] { 20, 40, 80, 100, 200 })
        .ButtonCount(5))
                        .ClientDetailTemplateId("TestTemplate")
        .DataSource(dataSource => dataSource
            .Ajax()

            .PageSize(10)
                    .Read(read => read.Action("TestAction", "TestController"))
        )
                        )
                        <script id="TestTemplate" type="text/kendo-tmpl">
                            @(Html.Kendo().Grid<FW.Model.model1>()
                .Name("ChildGrid#=Id#") // template expression, to be evaluated in the master context
.Columns(col =>
{
    col.Bound(o => o.Id).Hidden(true);

    col.Bound(o => o.name).Width(100).ClientTemplate("\\#= BuildLink(data,'1') \\#");
    col.Bound(o => o.testName).Width(100).ClientTemplate("\\#= BuildLink(data,'2') \\#");
    col.Bound(o => o.TestName1).Width(100).ClientTemplate("\\#= BuildLink(data,'3') \\#");       
})
.Filterable(x=>x.Mode(GridFilterMode.Row))
                        .Scrollable()
                .DataSource(dataSource => dataSource
                .Ajax()
                                .Read(read => read.Action("TestAction2", "TestController2", new { Id= "#=Id#", maxCalls = "#=MaxCalls#" }))
                    ).Events(events => events.DataBound("DataBound_AllCallChild"))

            .ToClientTemplate()
                            )
                        </script>
                    </div>
                </div>
            </div>
        </div>

    </div>
</div>

在这里查看.Filterable(x=>x.Mode(GridFilterMode.Row)) 我是如何应用过滤器的，我在这里使用了重载函数并使用了 GridFilterMode.Row 而不是 GridFilterModel.menu。

希望这会有所帮助！
