    Set multinode treepicker value programmatically in Umbraco 7.10

    How do I set the value for a multinode treepicker in c#. I found the post from 2015: https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/71722-setvalue-in-multi-node-tree-picker but it doesn't seem to work. Here is my code:

                    var doc = contentServices.GetById(item.Id);
                doc.SetValue("schedule", page.Id+",7190");
                contentServices.SaveAndPublishWithStatus(doc);
                umbraco.library.RefreshContent();
                var asd = doc.GetValue("schedule");

    I get 'doc' properly and when I check the value of 'asd' with a breakpoint, it is as I set it with 'SetValue', but when i finish the process and look at my backoffice, multinode treepicker is still empty.

    I'm building it based on its GUID:

    List<string> otherCategoriesList = new List<string>();
foreach (var otherCategory in post.OtherCategories) {

    IPublishedContent catNode = rootNode.Descendants().Where(x => x.Name == otherCategory).FirstOrDefault();
    var guid = contentService.GetById(catNode.Id).GetUdi().Guid;
    otherCategoriesList.Add(string.Concat("umb://document/", guid.ToString().Replace("-", "")));
}

postContent.SetValue("otherCategories", string.Join(",", otherCategoriesList));

    Thanks for this answer, saved me some time ;)

    Btw, you can make your code a little bit faster and safer like this:

     List<string> otherCategoriesList = new List<string>();
                IEnumerable<IPublishedContent> descendants = rootNode.Descendants();
                foreach (var otherCategory in post.OtherCategories) {

                    IPublishedContent catNode = descendants.FirstOrDefault(x => x.Name == otherCategory);
                    if (catNode != null) {
                        otherCategoriesList.Add(contentService.GetById(catNode.Id).GetUdi().ToString());
                    }
                }

                postContent.SetValue("otherCategories", string.Join(",", otherCategoriesList));

    A note that the guid key shouldn't include - chars

    For example when you get some records by contentService:

    var contents = Services.ContentService.GetByIds([Ids]);

    Then you want to get the value to set to multinode treepicker property, you will do this:

    var valueToSet = string.Join(",", contents.Select(e => "umb://document/" + e.Key.ToString().Replace("-", "")));

    Hope it help.

    Cheers.
