Is there any property or method to get the list of child publications of a particular publication using core service?
Thanks, Jey
As per my answer in this previous question, "Where Used" is your friend.
client.GetList(publicationId, new UsingItemsFilterData());
gives you a list of items which "use" the publication, i.e. it's children.
The list will include all of the descendant publications. If you want only the direct children then you can loop over each publication in the list and check it's parents. See my other answer for an example of how to do that.
filter.ForItem
(i.e. page/component) where you need to usefilter.ForRepository
for the publication?
