Hi Craig

You can of course traverse the content tree using Children() or Descendants(). However Descendants() should be avoided when possible - especially when having a large content tree with many nodes and levels.

I would be much better to using XPath - you can easily find all nodes below a specific folderdocument type.

var xpath = "//Folder/*";

or from a specific root node:

var xpath = string.Format(@"//Folder[ancestor::Home[@id = ""{0}""]]/*", rootNodeId);

You should then be able to use UmbracoHelper to get the nodes from XPath. Something like this:

var nodes = Umbraco.TypedContentAtXPath(xpath).OrderBy(x => x.GetPropertyValue<DateTime>("createDate")).Take(3);

Hi Bjarne,

Thanks for your reply :) I've attempted your solution but sadly I'm getting no results (and there's loads of content under the content node).

I've attached a screenshot of my code and the results in case I've missed something obvious (just to confirm the node 1100 is a document type as oppose to a folder.).

Thanks again, Craig

Hi Craig,

Folder in the XPath should be the folder node's DocumentTypeAlias (just in case that wasn't obvious from Bjarnes post).

Also - which type (DocumentTypeAlias) do you want to end up selecting?

E.g.. this XPpath should get you any NewsItem that's inside or below any Folder node below the node with id=1100:

var xpath = string.Format("id({0})//Folder//NewsItem", 1100);

Hope that helps,

Hi Chriztian,

Thanks for your help sadly I'm still getting no results :(

What I've got is:

var xpath = string.Format("id({0})//uBlogsyLanding//uBlogsyPost", 1100);

The Node ID of 1100 relates to the root node of the uBlogsyLanding page and I'm trying to extract the last three posts that live under this node.

Here's a screenshot of my content tree.

Thanks my friend.

A ha, beautiful work gents :)

Thanks for your assistance

Hi again,

Just one more thing I think that this is giving the oldest 3 posts first as opposed to the latest 3. I can't seem to get a desc or reverse to work?

Thanks, C

Hi Craig,

There is a OrderByDescending method. That would do the trick.

If you want really superfast speed you can use a xpath navigator.

You can see a example of what your are looking for here : https://www.slideshare.net/dawoe/the-need-for-speed-uk-fest on slide 55

This uses models builder so you can ditch the .OfType<NewsDetailpage>

Dave

Thanks Dave,

Strange one this as orderby and orderbydescending both remove the latest posts as opposed to the oldest ones...

var nodes = Umbraco.TypedContentAtXPath(xpath).OrderBy(x => x.GetPropertyValue

var nodes = Umbraco.TypedContentAtXPath(xpath).OrderByDescending (x => x.GetPropertyValue

Both produce the same results......

Hi Craig,

Can you try this :

var nodes = Umbraco.TypedContentAtXPath(xpath).OrderByDescending (x => x.GetPropertyValue<DateTime>("createDate")).Take(3);

So the property is actually converted to a date when ordering ?

Dave

Sorry yes,

That produces the same results i.e. OrderBy and OrderByDescending return identical posts.

Hi Craig,

Is createDate a actually property on your doctype ?

Or do you just want to sort on the create date of the content item?

Dave

Hi Dave,

I thought that createDate related to the datestamp of the content item creation date??

Is that not the case?

C

Hi Craig,

Can you try this :

var nodes = Umbraco.TypedContentAtXPath(xpath).OrderByDescending (x => x.CreateDate).Take(3);

This will sort on the create date of the content item

Dave

Perfect!

I'm such a loser!

Thanks for your time my friend

No problem mate....We all have been there once.

A fresh pair of eyes sometimes can see the obvious.

Dave
