Then you'll want to use
Eval("NodeAlias")
This will get you the URL friendly name used for that document. Again, for the reason I mentioned above AND the fact that Kentico will remove/replace any non-url friendly characters in this field whereas the DocumentName or ArticleName fields will allow those non-friendly URL characters.
You can find all the fields available simply by running the view for the corresponding document type. For instance if you're looking for the article fields run:
SELECT *
FROM View_CONTENT_Article_Joined
You can get any doc type's information by following this methodology:
View_<namespace>_<classname>_Joined
