TreeView PHP Class Overview

The Kendo UI TreeView for PHP 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.

Step 1 Make sure you followed all the steps from the introductory article on Telerik UI for PHP—include the autoloader, JavaScript, and CSS files.

Step 2 Create a TreeView, configure its items.

Example
    <?php
    $treeview = new \Kendo\UI\TreeView('treeview');

    $root = new \Kendo\UI\TreeViewItem('Root');
    $root->expanded(true);

    $child = new \Kendo\UI\TreeViewItem('Child');
    $root->addItem($child);

    $treeview->addItem($root);
    ?>

Step 3 Output the TreeView by echoing the result of the render method.

Example
    <?php
    echo $treeview->render();
    ?>

Event Handling

You can subscribe to all TreeView events.

Specify Function Names

The example below demonstrates how to subscribe for events by specifying a JavaScript function name.

Example
    <?php
    $treeview = new \Kendo\UI\TreeView('treeview');

    // The 'treeview_collapse' JavaScript function will handle the 'treeview_collapse' event of the treeview
    $treeview->collapse('treeview_collapse');

    echo $treeview->render();
    ?>
    <script>
    function treeview_collapse() {
        // Handle the collapse event
    }
    </script>

Provide Inline Code

The example below demonstrates how to provide inline JavaScript code.

Example
    <?php
    $treeview = new \Kendo\UI\TreeView('treeview');

    // Provide inline JavaScript code that will handle the 'collapse' event of the treeview
    $treeview->collapse('function() { /* Handle the collapse event */ }');

    echo $treeview->render();
    ?>

Reference

Client-Side Instances

You can reference the client-side Kendo UI TreeView instance via jQuery.data(). Once a reference is established, use the TreeView API to control its behavior.

Example
    <?php
    $treeview = new \Kendo\UI\TreeView('treeview');
    echo $treeview->render();
    ?>
    <script>
    $(function() {
        // The constructor parameter is used as the 'id' HTML attribute of the treeview
        var treeview = $("#treeview").data("kendoTreeView")
    });
    </script>
