    Is there a way to cancel the click on a menu item in the OnClientItemClicked event?

    The documentation says you can by returning a false from the handler but I can seem to get it to work.

    Here is a routine i wrote to cancel the postback if the user hits the cancel button on the confirm window 

    function RADItemClicked(sender, eventArgs)
        var item = eventArgs.get_item();
        if(item.get_text()=="Save Changes") {
            if (!confirm("Save Changes?")) { return false }

    Not sure what im doing wrong. Any advise would be appreciated.

    Hello Robert Verderber,

    I suggest that you subscribe to the OnClientItemClicking event. In its event handler you can check the text of the clicked item and use set_cancel(true) to cancel the event.

    Here is how your event handler can be defined:

    function onClientItemClicking(sender, eventArgs)  
        var item = eventArgs.get_item();  
        if(item.get_text()== "Save Changes") {  
            if (!confirm("Save Changes?")) { eventArgs.set_cancel(true); }  

    <telerik:RadMenu ID="RadMenu1"   

    I hope this helps.

    Kind regards,
    the Telerik team

    why return false did not work! I have it working with your fix.

    It works for the classic RadMenu version.
