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>
