Hello David,

I was not able to reproduce the behaviour that you're seeing on your side. I have attached the sample project I used to test this. Please test this project on your side; whether or not it works correctly may help indicate the nature of this issue. 

If this sample project is not an accurate demonstration of what you're trying to do, please feel free to modify it and send it back, or send a small sample project of your own if you have one.
Please let me know if I can provide any further assistance.

Unfortunately I spoke too soon, As soon as I try modify the control (to set up columns, etc), errors are shown.  Closing the view and then re-opening the view causes the errors to disappear, but they re-appear again as soon as I try edit the view.  I have attached an image which shows the view mark-up and one of the errors ('ID' is not a member of System.Web.Mvc.MvcHtmlString)

Any ideas?

Thanks Denis - that really helped.  I got all my packages inline with your example to make sure my references were the same, cleaned the solution, got the web.config files cleaned up, rebuilt and voila!  Appreciate the help!
