    How can I add an item to nested-content (IEnumerable<IPublishedElement>>("usps")) programmatically?

    Using Umbraco And Getting Started
    Umbraco 8

    I have usps nested-content property on-page and I want to add a new item to usps list from backend

    The item property name is usp

    Thanks in advance.

    Hi Davit,

    Something like:

    var list = new List<Dictionary<string, string>>();

Guid guid1 = Guid.NewGuid();

liste.Add(new Dictionary<string, string>(){
    {"key","@guid1"},
    {"name","Some name"},
    {"ncContentTypeAlias","usp"},
    {"Property in NestedContent","Some Text"},
});

node.SetValue("usps", JsonConvert.SerializeObject(list));

    Thanks,

    Alex

    I am having almost the same code as that @Alex has advice.

    var cs = Services.ContentService;
var Parent = cs.GetById(Convert.ToInt32(NodeId));

var uLikes = new List<Dictionary<string, string>>();

uLikes.Add(new Dictionary<string, string>() {
            {"ncContentTypeAlias","userPost"},
            {"key", new Guid.NewGuid().ToString() },
            {"mUser", UserGUID().ToString()}, // get Members ID

        });

            Parent.SetValue("post", Newtonsoft.Json.JsonConvert.SerializeObject(uLikes));

 cs.SaveAndPublish(Parent);

    But the issue is every time it overwrites the Old Value with the new one. As I need to append/add new Items to nested content!

    so how can I do so?

    Thanks

    BJ

    You are creating a new uLikes object every time and saving it.

    You need to get the existing uLikes object, deserialize it, add your new Dictionary item, and then save this updated uLikes value.
