Getting Started

Configuration

Below are listed the steps for you to follow when configuring the Kendo UI TreeView for binding to data, passed as a model attribute in Spring MVC.

Step 1 Make sure you followed all the steps from the introductory article on Telerik UI for JSP.

Step 2 Create a new action method and pass the Category list to the View.

    @RequestMapping(value = "/local-data", method = RequestMethod.GET)
    public String index(Locale locale, Model model) {
        model.addAttribute("categories", categories.getList());

        return "web/treeview/local-data";
    }

Step 3 Add the Kendo UI taglib mapping to the page.

    <%@taglib prefix="kendo" uri="https://www.telerik.com/kendo-ui/jsp/tags"%>

Step 4 Add a server-bound TreeView.

    <kendo:treeView name="categoriesTreeView">
        <kendo:dataSource data="${categories}" />
    </kendo:treeView>

Event Handling

Subscribe to Events

You can subscribe to all events exposed by Kendo UI TreeView by the handler name.

  <kendo:treeView name="categoriesTreeView" select="category_select">
      <kendo:dataSource data="${categories}" />
  </kendo:treeView>

  <script>
      function category_select) {
          // Handle the select event
      }
  </script>

Reference

Existing Instances

You are able to reference an existing TreeView instance via the jQuery.data(). Once a reference is established, you are able to use the TreeView API to control its behavior.

  // Put this after your Kendo UI TreeView tag declaration
  <script>
  $(function() {
      // Notice that the name attribute of the treeview is used to get its client-side instance
      var treeview = $("#categoriesTreeView").data("kendoTreeView");
  });
  </script>
