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

The client-side OnClientNodeClicking event of the RadNavigation is raised when the user attempts to click on a Node. To handle this event, simply write a JavaScript function that can be called when the event occurs. Then assign the name of this function as the value of the OnClientNodeClicked property. This event could be canceled and the technique for achieving this is demonstrated in Example 1.

The client-side OnClientNodeClicking event handler receives two arguments:

  • sender — the RadNavigation object that fired the event.

  • Event arguments — an event arguments object that exposes the following methods:

ButtonClicking Event Arguments Object

Name Parameters Return Type Description
get_cancel() bool Gets a value that indicates whether the event is canceled.
get_node() Telerik.Web.UI.NavigationNode Returns an instance of NavigationNode that has just been clicked.
set_cancel(value) bool Sets whether the event will be canceled (if true is passed).

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

<script type="text/javascript">
    function OnClientNodeClicking(sender, eventArgs) {
        var clickedNodeText = eventArgs.get_node().get_text();
        if (clickedNodeText == "Node2") {

<telerik:RadNavigation runat="server" ID="RadNavigation1" OnClientNodeClicking="OnClientNodeClicking">
        <telerik:NavigationNode Text="Node1"></telerik:NavigationNode>
        <telerik:NavigationNode Text="Node2"></telerik:NavigationNode>
        <telerik:NavigationNode Text="Node3"></telerik:NavigationNode>
