Code for using page properties as Dynamic Properties in EPiServer and retrieve their values up the chain.

Implements the similar logic as Anders Hattestad proposes in this blog post: http://world.episerver.com/Blogs/Anders-Hattestad/Dates/2013/8/Using-Page-Properties-as-dynamic-properties-in-EPiServer-7/

Code is provided as is. If you use it you might consider doing some nice null- and empty checks, or your project probably will break.

FindProperty.cs

using EPiServer;
using EPiServer.Core;
using EPiServer.ServiceLocation;

namespace Core.Properties
{
    public static class PropertyFinder
    {

        public static T FindProperty<T>(PageData currentPage, string propertyName) 
        {
            if (currentPage[propertyName] != null) {
              return (T)currentPage[propertyName];              
            }

            var contentRepository = ServiceLocator.Current.GetInstance<IContentRepository>();
            var parentPage = contentRepository.Get<PageData>(currentPage.ParentLink);

            if (parentPage == null) {
                return default(T);
            }

            if (parentPage[propertyName] != null) {
                return (T)parentPage[propertyName];                
            }

            return FindProperty<T>(parentPage, propertyName);
        }
    }
}

ViewModel.cs

private MyPropertyType _myInheritedProperty;
public MyPropertyType MyInheritedProperty
{
    get
    {
        if (_myInheritedProperty == null)
        {
            _myInheritedProperty = Core.Properties.PropertyFinder.FindProperty<MyPropertyType>(CurrentPage, "MyInheritedProperty");
        }
        return _myInheritedProperty;
    }
}
