    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);
    }
