Row Click-Move-Click

As of Kendo UI R2 SP1 2023, users can reorder the TreeList's rows can be by using the click-move-click functionality provided by the clickMoveClick option. To start moving the row, users can click the drag icon, and then click again to place the row in its new position.

    <div id="treeList"></div>
    <script>
    $("#treeList").kendoTreeList({
        columns: [
            {draggable:true },
            { field: "name" },
            { field: "age" }
        ],
        editable: {
            move: {
              reorderable: true,
              clickMoveClick: true
            }
        },
        dataSource: {
        data: [
            { id: 1, parentId: null, name: "Jane Doe", age: 22 },
            { id: 2, parentId: 1, name: "John Doe", age: 24 },
            { id: 3, parentId: null, name: "Jenny Doe", age: 14 }
        ]
        }
    });
    </script>

Editing by Dragging and Dropping

Currently, the dragging and dropping of items (editable.move = true and editable.move.reorderable) is not supported with the incell edit mode of the TreeList because the draggable functionality prevents the mousedown event. As a result, the change event of the editor input does not fire, which in turn prevents the MVVM binding from saving the updated value. To work around this problem, refer to this GitHub issue.

When the editable.move option is set to true, the user can drag and drop the rows and the TreeList internally updates the parentId field. Setting the editable.move.reorderable property to true enables users not only to move items to a different level in the hierarchy but also allows users to reorder items within a particular hierarchy level.

To persist the new hierarchy, configure the TreeList data source for CRUD operations and set transport.update as a bare minimum. For a runnable example, refer to the demo on editing by dragging and dropping the rows of the TreeList.

The following example demonstrates how to enable the batch data source and the editable move configuration.

    <div id="treelist"></div>

    <script>
        $(document).ready(function () {
            var crudServiceBaseUrl = "https://demos.telerik.com/kendo-ui/service";

            var dataSource = new kendo.data.TreeListDataSource({
                    transport: {
                        read:  {
                            url: crudServiceBaseUrl + "/EmployeeDirectory/All",
                            dataType: "jsonp"
                        },
                        update: {
                            url: crudServiceBaseUrl + "/EmployeeDirectory/Update",
                            dataType: "jsonp"
                        },
                        parameterMap: function(options, operation) {
                            if (operation !== "read" && options.models) {
                                return {models: kendo.stringify(options.models)};
                            }
                        }
                    },
                    batch: true,
                    schema: {
                        model: {
                            id: "EmployeeId",
                            parentId: "ReportsTo",
                            fields: {
                                EmployeeId: { type: "number", editable: false, nullable: false },
                                ReportsTo: { nullable: true, type: "number" },
                                FirstName: { validation: { required: true } },
                                LastName: { validation: { required: true } },
                                HireDate: { type: "date" },
                                Phone: { type: "string" },
                                HireDate: { type: "date" },
                                BirthDate: { type: "date" },
                                Extension: { type: "number", validation: { min: 0, required: true } },
                                Position: { type: "string" }
                            },
                            expanded: true
                        }
                    }
                });

            $("#treelist").kendoTreeList({
                dataSource: dataSource,
                toolbar: [ "save" ],
                editable: {
                    move: true
                },
                height: 540,
                columns: [
                    { field: "FirstName", expandable: true, title: "First Name", width: 220 },
                    { field: "LastName", title: "Last Name", width: 100 },
                    { field: "Position" },
                    { field: "HireDate", title: "Hire Date", format: "{0:MMMM d, yyyy}" },
                    { field: "Phone", title: "Phone" },

                ]
            });
        });
    </script>
