TreeList JSP Tag Overview

The TreeList JSP tag is a server-side wrapper for the Kendo UI TreeList widget.

Getting Started

Configuration

Below are listed the steps for you to follow when configuring the Kendo UI TreeList.

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 which renders the view.

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

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

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

Example
    <%@taglib prefix="kendo" uri="http://www.kendoui.com/jsp/tags"%>

Step 4 Add a server-bound TreeList.

Example
    <kendo:treeList name="employees" pageable="true">
        <kendo:treeList-columns>
            <kendo:treeList-column title="Product Name" field="productName" />
            <kendo:treeList-column title="Unit Price" field="unitPrice" format="{0:c}" />
            <kendo:treeList-column title="Units In Stock" field="unitsInStock" />
        </kendo:treeList-columns>
        <kendo:dataSource data="${products}" pageSize="10"/>
        <kendo:treeList-pageable input="true" numeric="false" />
    </kendo:treeList>

Event Handling

Subscribe to Events

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

Example
  <kendo:treeList name="employees" dataBound="employees_dataBound" change="employees_change">
      <kendo:dataSource data="${data}" pageSize="10"/>
  </kendo:treeList>

  <script>
  function employees_dataBound() {
      //Handle the dataBound event
  }

  function employees_change() {
      //Handle the change event
  }
  </script>

Reference

Existing Instances

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

Example
  //Put this after your Kendo TreeList tag declaration
  <script>
  $(function() {
      // Notice that the name attribute of the treelist is used to get its client-side instance
      var treelist = $("#employees").data("kendoTreeList");
  });
  </script>
