Sorting nodes in content tree

I have a bit of an unusual sorting need for the project I'm working on and I was wondering: is it possible to use the API to sort nodes in the content tree?

If not, I'll have to look at a different approach, but it would be super nice if this was possible.

You can set the SortOrder Property of the Documents by api:

umbraco.cms.businesslogis.web.Document doc = new umbraco.cms.businesslogis.web.Document(NODEID);
doc.sortOrder = 10;
doc.Publish(user);
umbraco.library.UpdateDocumentCache(doc.Id);

Cool! I'll have to loop through all the nodes myself and sort them, so no autosorting functions?

I think so, I think the autosorting feature is only in the backend.

Implement your own comparer (in this example sorting by Expiration Date):

using umbraco.cms.businesslogic.web;
 
    public class MyDocumentComparer: IComparer<Document>
    {
        public int Compare(Document x, Document y)
        {
            return x.ExpireDate.CompareTo(y.ExpireDate);
        }
    }

and then compare the nodes:

Document parentDoc = new Document(parentId);
List<Document> childs = new List<Document>();
childs.AddRange(parentDoc.Children);
childs.Sort(new MyDocumentComparer());

hth, Thomas

Sweet! Thanks for taking the time to look that up Thomas. Not sure I can use this as I have some specific needs, but I'll look into it!

Gald I coudl help.

You can extend the Comparer with your own code. To compare some properties just compare them and return 1 for x > y, -1 for x<y and 0 for x = y

Thanks for your posts, guys, they really helped me out. This is how I sorted my documents:

Document parent = new Document(sender.Parent.Id);
List<Document> siblings = new List<Document>();
siblings.AddRange(parent.Children);

siblings.Sort(new MyComparer());

for (int i = 0; i < siblings.Count; i++)
{
    siblings[i].sortOrder = i;

    if (siblings[i].Published || siblings[i].Id == sender.Id)
        siblings[i].Publish(sender.User);
    else
        siblings[i].Save();

    library.UpdateDocumentCache(siblings[i].Id);
}
