We are working on updating User and Dev manuals. To configure NewsView control to display the whole info of an item to a different page you could do the following
1. Create a page where you have NewsView control( for example pageWithNewsView) which will list all items. Generally when you have added the control and clink on any item you are redirected to http://yourwebsite/pageWithNewsView/[Publication_Date]/Tite.aspx
( it is the url format which tells the parser how to form links)
2. Create a second different page - NewsItemDetails which will hold the full info. You should add NewsView control to this page. Then, when you click on an item a link will be:
Instead of 'Use a page especially prepared to hold the full info" option you could use SingleItemUrl property wich can be found at Advanced mode of NewsView control, Section Explicit links.
You can work with control Behavior Mode - Master, Detail, Auto. - On your NewsItemDetails page you can set NewsView control to use Detail mode, so that no items will be visible on this page until someone hits news item link from pageWithNewsView.aspx.
All the best,
