Hi Yoni,

You could use the Content Type service in order to find a list allowed content types if you know the document type's alias. I haven't tested the following helper method but it should give you an idea as to how you can do it:

using System.Collections.Generic;
using System.Linq;
using Umbraco.Core;
using Umbraco.Core.Models;

namespace Application
{
    public class ContentTypeHelper
    {
        public IEnumerable<IContentType> GetAllowedContentTypes(string alias)
        {
            var retval = new List<IContentType>();

            if (string.IsNullOrWhiteSpace(alias)) 
                return retval;

            // Use the content type service to find
            // the content type passed to the method
            var contentTypeService = ApplicationContext.Current.Services.ContentTypeService;
            var contentType = contentTypeService.GetContentType(alias);

            if (contentType == null) 
                return retval;

            // If we have found the content type, loop through 
            // each of it's allowed content types and select
            // the content type
            retval.AddRange(
                contentType.AllowedContentTypes.Select(
                    ct => contentTypeService.GetContentType(ct.Id.Value)));

            return retval;
        }
    }
}

So in your instance, you could use the above method as follows:

var allowed = ContentTypeHelper.GetAllowedContentTypes("Homepage");

Hope that helps.

Thanks, Dan.
