    CS0029: Cannot implicitly convert type 'System.Guid' to 'Umbraco.Core.Udi'

    Extending Umbraco and using the API
    Umbraco 8

    I are trying to auto create a Content Node as a sub node when ever a particular document type is added o the content.

    Example would be a content Node (sub node) every time a new page node is created.

    but I keep getting stuck with the parent node Id.

    an error simalar to below comes up

    CS0029: Cannot implicitly convert type 'System.Guid' to 'Umbraco.Core.Udi'

    on this line of code

    var newContent = cs.CreateContent("Components", key, "iBDComponentList");

    The error changes dependent on how or what you pass in place of "key"

    according to documentation I should be able to just use elem.Id.

    below is the context of the code around it.

            private void ContentService_Saving(IContentService cs, ContentSavingEventArgs e)
        {
            foreach (var elem in e.SavedEntities.Where(n => n.WasPropertyDirty("Id") &&
                 ((n.ContentType.Alias == "iBDHome" ||
                   n.ContentType.Alias == "iBDPage") &&
                   n.WasPropertyDirty("Id"))))
            {
                Udi key = elem.Key;

                var newContent = cs.CreateContent("Components", key, "iBDComponentList"); 
                cs.Save(newContent);
            }
        }

    Hi Daniel

    elem.Key - is Guid, not Udi. Try this code:

    private void ContentService_Saving(IContentService cs, ContentSavingEventArgs e)
        {
            foreach (var elem in e.SavedEntities.Where(n => n.WasPropertyDirty("Id") &&
                 ((n.ContentType.Alias == "iBDHome" ||
                   n.ContentType.Alias == "iBDPage") &&
                   n.WasPropertyDirty("Id"))))
            {
                Guid key = elem.Key;

                var newContent = cs.CreateContent("Components", key, "iBDComponentList"); 
                cs.Save(newContent);
            }
        }

    CS1503: Argument 3: cannot convert from 'System.Guid' to 'Umbraco.Core.Udi'

    Have just updated to 8.1.

    Solved

    I need to be using ContentService_Saved as I wouldnt have a parent Id to link the sub document to.

    Using this allowed acces to the Udi 

    private void ContentService_Saved(IContentService sender, ContentSavedEventArgs e)
    {
        foreach (var elem in e.SavedEntities.Where(n => n.WasDirty() &&
             ((n.ContentType.Alias == "iBDHomePage" ||
               n.ContentType.Alias == "iBDStandardPage"))))
        {
            var umbracoParentGuid = elem.GetUdi();
            var publishDate = DateTime.Now;
            var name = "Components";
            var docType = "iBDPageComponents";


            IContent content = sender.CreateContent(name, umbracoParentGuid, docType,-1);
            content.CreateDate = publishDate;
            content.UpdateDate = publishDate;

            sender.SaveAndPublish(content);
        }
    }

    I'm just going to leave this for someone else who might find it useful. This applies to those who have or know the parent node (parentNode).

    To create a new node using CreateContent:

    var contentService = Current.Services.ContentService;
var udi = new GuidUdi(parentNode.ContentType.ItemType.ToString(), parentNode.Key);
var newNode = contentService.CreateContent(name, udi, contentTypeAlias);
contentService.Save(newNode);

    or create a new node with the Create method using the Key attribute to create a GUID:

    var contentService = Current.Services.ContentService;
var parentId = new Guid(parentNode.Key.ToString());
var newNode = contentService.Create(name, parentId, contentTypeAlias);
contentService.Save(newNode);

    I hope this helps you.
