@Aksel Sorry to necro this thread, but I am trying to render a block list within a block grid. I'm new to Umbraco and have probably just messed it up. I have the Back Office set up and working (using a content pick to pick from a library in Content and placing that item in Block List). How is it you are rendering in your view from a Block Grid. I have:
"`@inherits Umbraco.Cms.Web.Common.Views.UmbracoViewPage
@Model.Content.Value("contentBlockList")`"
where
contentBlockList
is my element type property in the data type.
