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.
@RequestMapping(value = "index", method = RequestMethod.GET)
public String index() {
return "web/panelbar/index";
}
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 the panelbar tag.
<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.
<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.
//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>
