How to programmatically get list of children

Cesar Pinilla asked on May 2, 2014 15:48

Hello, I'm trying to programmatically find all the children of a specific page in my content tree.

I've used both DocumentContext.CurrentDocument.Children and DocumentContext.CurrentDocument.AllChildren but neither seems to work consistently. If i'm logged in to the admin area, it seems to work, but if I'm viewing the page publicly (without logging in) they always return empty.

Thanks, Cesar

Hi,

If you want to know the "number" of children which will work for non-logged users as well you can also use the macro:

{%CurrentDocument.NodeChildNodesCount|(identity)GlobalAdministrator%}

I should add that all pages are published so it's not a publishing issue

You can use DocumentHelper.GetDocuments("CMS.MenuItem").Path(DocumentContext.CurrentDocument.NodeAliasPath, PathTypeEnum.Children)

Thank you all this worked! What is the reason behind .Children and .AllChildren not working?

Hi,

The reason is that there is a permission check when accessing the child documents like this. It basically requests the given documents and then counts them, but this should not be possible because you could access also other properties which might be a security issue.

There is a web.config key which disables this security check, but its better to use the code above in this case.

Kind regards,

Richard Sustek
