TreeList JSP Tag Overview
The TreeList JSP tag is a server-side wrapper for the Kendo UI TreeList widget.
Getting Started
Configuration
The names of the properties are case-sensitive,
productNameis different fromProductName.
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.
@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.
<%@taglib prefix="kendo" uri="https://www.telerik.com/kendo-ui/jsp/tags"%>
Step 4 Add a server-bound TreeList.
<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="${products}" pageSize="10"/>
<kendo:treeList-pageable input="true" numeric="false" />
</kendo:treeList>
Event Handling
Subscribe to Events
You can subscribe to all events exposed by Kendo UI TreeList by the handler name.
<kendo:treeList name="employees" dataBound="employees_dataBound" change="employees_change">
<kendo:dataSource data="${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.
//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>
