Gets or sets the loaded flag of the Node. Setting the loaded flag to false allows the reloading of child items.

Example - reload child nodes

var dataSource = new kendo.data.HierarchicalDataSource({
    transport: {
        read: {
            url: "https://demos.telerik.com/kendo-ui/service/Employees",
            dataType: "jsonp"
  schema: {
    model: {
      id: "EmployeeId",
      hasChildren: "HasEmployees"

dataSource.fetch(function() {
  var node = dataSource.at(0);
  node.load(); // load the child nodes
  node.loaded(false); // clear the loaded flag
  node.load(); // load the child nodes again
