In our code we were using this a lot in v7:
UmbracoHelper umbraco = new UmbracoHelper(UmbracoContext.Current);
IPublishedContent node = umbraco.Content(nodeId);
But for v8 I cannot find any documentation on how to do this the new way. I just want to grab a node as IPublishedContent in back-end code...
Can anyone help me with this?
I think this should all be using Dependency Injection now, but there is a static method on the Current object (you may need to add a reference):
This may not be the 100% spot on syntax but there is definitely a way of accessing an umbraco helper on this object.
the umbraco context can be called in a similar way.
I will update this with the actual code when i am back at my PC
But please don't use Current - in most places you will use this kind of code (like an API controller, or a SurfaceController, etc). you can just access these things already:
IPublishedContent node = this.UmbracoContext.ContentCache.GetById(1234);
If that's not available you can almost always get the UmbracoContext through dependency injection, I wrote a bit more about that over here:
Happy to look at some code if you can't figure it out!
Ah.. it's even easier, if you're using any of our base classes like SurfaceController etc. then you just do:
IPublishedContent content = Umbraco.Content(1234);
@Sebastiaan, IContentService as parameter for constructor seems to work, but when adding UmbracoHelper to constructor the magical dependency injection doesn't seem to work ("Boot failed")
Is there any way to get UmbracoHelper available in IComponent ?
@Remko - I understand from Stephane that you're not actually meant to try to get an UmbracoHelper in an IComponent, so the question is: what do you need it for?
I'm guessing the most common scenario would be to query some content, in which case you can inject IUmbracoContextFactory and get an umbracoContext from it, the safe way to do that (in case the context does not exist yet) is to Ensure it exists first:
private readonly IContentService _contentService;
private readonly IUmbracoContextFactory _context;
public MyComponent(IContentService contentService, IUmbracoContextFactory context)
_contentService = contentService;
_context = context;
public void Initialize()
using (var cref = _context.EnsureUmbracoContext())
var cache = cref.UmbracoContext.ContentCache;
var node = cache.GetById(1234);
I'm also looking to get an instance of UmbracoHelper, but in a custom service.
The reason for me, which means I can't use the content cache, is that I need to get the current page. Usually, I would get AssignedContentItem from the Umbraco helper.
Is there another way to get the current page?
I need to get access to UmbracoHelper within a class which inherits from PropertyValueConverterBase.
The reason is to access GetDictionaryValue.
Following the dependency injection approach I cannot inject UmbracoHelper into my class constructor.
This crashes Umbraco with error:
Boot failed: Umbraco cannot run. See Umbraco's log file for more details.
-> Umbraco.Core.Exceptions.BootFailedException: Boot failed.
-> System.NullReferenceException: Object reference not set to an instance of an object.

Anyone know how to get access to UmbracoHelper or Dictionary values from my PropertyValueConverter class?
