PanelBar JSP Tag Overview

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

Getting Started

Configuration

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

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 = "index", method = RequestMethod.GET)
    public String index() {

        return "web/panelbar/index";
    }

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 the panelbar tag.

Example
<kendo:panelBar name="panelBar" expandMode="single">
    <kendo:panelBar-items>
        <kendo:panelBar-item  text="My Teammates" expanded="true">
            <kendo:panelBar-item-content>
                <img src="/image_url" alt="Andrew Fuller" />
            </kendo:panelBar-item-content>
        </kendo:panelBar-item>
        <kendo:panelBar-item  text="Projects">
            <kendo:panelBar-items>
                <kendo:panelBar-item text="New Business Plan"/>
                <kendo:panelBar-item text="Sales Forecasts">
            </kendo:panelBar-items>
        </kendo:panelBar-item>
        <kendo:panelBar-item text="Communication" enabled="false"/>
    </kendo:panelBar-items>
</kendo:panelBar>

Event Handling

Subscribe to Events

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

Example
<kendo:panelBar name="panelbar" expand="panelbar_expand" collapse="panelbar_collapse">
    <kendo:panelBar-items>
        <kendo:panelBar-item text="Blog"></kendo:panelBar-item>
        <kendo:panelBar-item text="News" enabled="false"></kendo:panelBar-item>
    </kendo:panelBar-items>
</kendo:panelBar>

<script>
    function panelbar_expand() {
        //Handle the expand event
    }

    function panelbar_collapse() {
        //Handle the collapse event
    }
</script>

Reference

Existing Instances

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

Example
  //Put this after your Kendo PanelBar tag declaration
  <script>
  $(function() {
      // Notice that the Name() of the panelbar is used to get its client-side instance
      var panelbar = $("#panelbar").data("kendoPanelBar");
  });
  </script>
