Blocks / Content isn't directly linked to a page, they are held seperately

You need to when going to delete a page look at the content area(s) on that page and loop through and delete the blocks as well

The only issue with this is those blocks might be used on other pages, so you could cause issues doing this

Hi Swati,

Yikes—this sounds kinda risky. How’d you know a block is not being used elsewhere?

First thing, don’t use the DataFactory: you should be using the IContentRepository and dependency injection (DataFactory is legacy).

The closest approximation of what you want to do would be to use the IContentSoftLinkRepository, a very simple (read: untested) example would be:

// Get all the soft links for the specified page
var softLinks = _contentSoftLinkRepository.Load(page.PageLink).ToList();

// Use the Content Repository to load the content, filters to only the blocks
var blocks = _contentRepository.GetItems(softLinks.Select(x => x.ReferencedContentLink), new CultureInfo(language)).OfType<BlockData>();

Note that a block could be referenced a few different ways: in a ContentArea, in a list of ContentReferences, in a rich text area or as a ContentReference. The above example wouldn't return the block if it was reference via a ContentReference property (although this is potentially unlikely) because it wouldn't be a soft link.
