Thanks for your replies! After spending a bit more time with Kentico I realise that my needs are slightly different, and the question I asked was probably over complicating things.
What I'm really trying to do is to retrieve all pages of a certain type which have the same parent node.
Say I have a page type called 'link', and this is reused all over the place. In a particular view, I would like to be able to render a partial view that fetches all of the 'links' belonging to a certain parent node/page.
Does that make sense?
