Using Sharepoint 2010 Foundation. I have a number of custom list types I create in a feature. In the previous version, the types were visible on the quickLaunch by setting OnQuickLaunch = true inside the EventReceiver. In the new version we want to hide them. So I set OnQuickLaunch = false. However, the lists are still displayed on the QuickLaunch menu. Is there another setting I need to use to hide the custom lists from QuickLaunch programmatically?
