Unable to replace the left side navigation, to show only my metadata nagivation tree

Question

I was reading about showing the metadata navigation tree as my left side navigation, i found this link which describe how to implement a similar task http://markuspersson.wordpress.com/tag/managed-metadata/ . but when i added the following at the beginning of my EnterpriseWiki.aspx page using SharePoint designer :-

<%@ Register Src="/_Controltemplates/MetadataNavTree.ascx" 
                TagName="MetadataNav" 
                TagPrefix="SharePoint" %>

and the following at the end :-

<asp:Content ContentPlaceHolderID="PlaceHolderLeftNavBar" runat="server">
    <SharePoint:MetadataNav ID="Metadatanav1" runat="server" />
</asp:Content>

The navigation is shown as follow inside my SharePoint site link

So i have the following question:-

1. how i can show the full navigation tree.

2. how i can add a custom redirect inside my page layout or in some control ?

Thanks in advance for any help.

Answer 1

1. MetadataNavigationTree only displays when you are on a page/list/library which has Metadata configured - All Publishing lists and libraries has this as well as the system pages by default.

2. There exist many ways. Most common is a hidden webpart (HTML Form Web Part) with some javascript.
