Description

How can I dynamically add hierarchy levels to the Grid?

Solution

  1. Use the setOptions method of the Grid.
  2. In the setOptions properties, add the detailTemplate configuration and the detailInit event.
<div id="example">
    <button id="button">Create Hierarchy</button>
    <div id="grid"></div>

    <script type="text/x-kendo-template" id="template">
        <div class="orders"></div>
    </script>

    <script>
        $(document).ready(function() {
            var element = $("#grid").kendoGrid({
                dataSource: {
                    type: "odata",
                    transport: {
                        read: "https://demos.telerik.com/kendo-ui/service/Northwind.svc/Employees"
                    },
                    pageSize: 20,
                    serverPaging: true,
                    serverSorting: true
                },
                height: 550,
                sortable: true,
                pageable: false,
                columns: [{
                        field: "FirstName",
                        title: "First Name",
                        width: "120px"
                    },
                    {
                        field: "LastName",
                        title: "Last Name",
                        width: "120px"
                    },
                    {
                        field: "Country",
                        width: "120px"
                    },
                    {
                        field: "City",
                        width: "120px"
                    },
                    {
                        field: "Title"
                    }
                ]
            });

            $("#button").kendoButton({
                click: function(e) {
                    var grid = $("#grid").data("kendoGrid");
                    grid.setOptions({
                        detailTemplate: kendo.template($("#template").html()),
                        detailInit: detailInit
                    })
                }
            });

        });

        function detailInit(e) {
            var detailRow = e.detailRow;

            detailRow.find(".orders").kendoGrid({
                dataSource: {
                    type: "odata",
                    transport: {
