Simply RedDot: "Navigation Emulation"

written by Jian Huang, 7. December 2011
 

What is it?

Allow a page, even a non navigation page, to display the exact navigation area as displayed on any page.
 

Why is it useful?

When a page is not in navigation manager, the page cannot display navigation because it is not part of navigation manager.

However, a page should not be in navigation manager simply because it needs to display navigation. For example, news article pages should not be in navigation manager because number of navigation pages in navigation manager negatively impacts project performance.

However, news article pages must display navigation area for the shake of accessibility. Hence, news article page can use navigation emulation to emulate the navigation of its parent page, the new archive page. 
 

Simple Method

<!IoRangeDynLink>
<!IoRangeNoRedDotMode><!IoRangeRedDotMode><%anc_link%><!/IoRangeRedDotMode><!/IoRangeNoRedDotMode>
<%!! Navigation:OutputArea(LeftNavArea, Bool:True, Guid:<%inf_page_guid%> !!%>
<!/IoRangeDynLink>
