Hi Geovanny,

Thank you for report.
WebExplorerBar does not have an option to cancel navigation.

An application may get around by processing and canceling original "click" browser event.

The ClientEvents.ItemClick can not be used for that purpose, because it is raised not on "click" event, but on "mouseup". Since browser raises "click" after "mouseup", application may process ItemClick which provides reference to item and set the "cancel-click" flag, which will allow the click-handler to cancel event and prevent default navigation to A.href.

Below is example for you:

function WebExplorerBar1_Initialize(sender)
{
  $addHandler(sender.get_element(), 'click', function(e) {
     // cancel navigation by A.href
  if (sender._cancelClick)
     $util.cancelEvent(e)
     });
}
function WebExplorerBar1_ItemClick(sender, eventArgs)
{
    // reset cancel-navigation flag
    delete sender._cancelClick;
  // condition to cancel navigation by A.href
  if (!eventArgs.getExplorerBarItem().hasChildren()) {
    // set cancel-navigation flag 
    sender._cancelClick = true;
    UrlSelected(eventArgs);
     } else {return;}
}

<ig:WebExplorerBar ...>
  <ClientEvents ItemClick="WebExplorerBar1_ItemClick" Initialize="WebExplorerBar1_Initialize" ItemSelecting="WebExplorerBar1_ItemSelecting" />
  ...
</ig:WebExplorerBar>

Hi Viktor,

Thank you very much for answering. It's just what I need. See you next time!

Thanks.

Hi Geovanny,

For now it is not available yet. It will be available in coming service releases for 2012.1-2013.1, but not 2011.1. So, you may use work around.

Hi Viktor,

I'm using NetAdvantage 2011.1, Version=11.1.20111.1006. from What version of NetAdvantage is available this improvement?

Thanks

Geovanny Domínguez.

Hi Geovanny,

The WebExplorerBar.ClientEvents.ItemClick was improved and second param eventArgs will extend CancelEventArgs with get/set_cancel member methods. If application will call eventArgs.set_cancel(true), then that will disable navigation to NavigateUrl.

That improvement will be also available for NodeClick of WebDataTree, because WebDataTree is used as internal "engine" of WebExplorerBar.
