<script>
  var dataSource = new kendo.data.GanttDataSource({
    data: [
      {
        id: 1,
        orderId: 0,
        parentId: null,
        title: "Task1",
        summary: true,
        expanded: true,
        start: new Date("2014/6/17 9:00"),
        end: new Date("2014/6/17 11:00")

        parentId: null,
        title: "Task2",

    ]
  });

  dataSource.fetch();

  // returns a list with all tasks in the following order: [Task1, Task3, Task2]
  var childTasks = dataSource.taskTree();

Example - get all Gantt tasks when the parent is collapsed

<script>
  var dataSource = new kendo.data.GanttDataSource({
    data: [
      {
        id: 1,
        orderId: 0,
        parentId: null,
        title: "Task1",
        summary: true,
        expanded: false,
        start: new Date("2014/6/17 9:00"),
        end: new Date("2014/6/17 11:00")
      },
      {

        end: new Date("2014/6/17 11:00")
      }
    ]
  });

  dataSource.fetch();

  // returns a list with two tasks in the following order: [Task1, Task2]
  var childTasks = dataSource.taskTree();
</script>

Example - get all child tasks of the first task ordered by their hierarchical index

<script>
