The following article demonstrates how to use and subscribe to the OnClientLoad client-side event of the RadNavigation control.

The OnClientLoad event occurs after the RadNavigation has been fully initialized at the client-side.The event handler receives one parameter:

  • sender - the RadNavigation object that fired the event.

Example 1: Handle the RadNavigation's client-side OnClientLoad event.

<script type="text/javascript">
    function OnClientLoad(sender) {
        var navigation = sender;
        var nodesNumber = navigation.get_nodes().get_count();
        alert("The RadNavigation client-side object is fully loaded and the number of nodes is " + nodesNumber);

<telerik:radnavigation runat="server" id="RadNavigation1" onclientload="OnClientLoad">
        <telerik:NavigationNode Text="Node1"></telerik:NavigationNode>
        <telerik:NavigationNode Text="Node2"></telerik:NavigationNode>
        <telerik:NavigationNode Text="Node3"></telerik:NavigationNode>
