TreeView JSP Tag Overview
The TreeView JSP tag is a server-side wrapper for the Kendo UI TreeView widget.
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>
