Nested Properties in ASP.NET GridView or DetailsView

   Is there a way to get nested properties to work in the GridView and DetailsView BoundField object's (like Contact.Address.FullAddressHTML).  In the previous framework we converting from, all of our entities inherited from a base class that inherited from an object that implemented the ICustomTypeDescriptor interface which returned a custom "PropertyDescriptorCollection" class on the GetProperties method of ICustomTypeDescriptor which enabled us to use Nested Types. 

In the help files I see some reference to nested properties and databinding but I'm not sure if or how they can be used in an ASP.NET application.

Also, the ADO.NET EF framework doesn't easily allow one to define a custom base class which all other entities inherit from which common custom code could be put.  I don't see a way to do this in the current beta of DevForce EF, will there be a way in the next beta?  If I could do this, then I would just make this abstract base class implement the ICustomTypeDescriptor class like we current have but without this, I would have to do this on all my entities and I really don't want to have to do that.

Thanks,

Dan
