I had the same issue when used Ajax.BeginForm, where i needed to return a partial view, but all the modelstate errors were gone. what does the trick is to isolate the Ajax.BeginForm part to a separate View, and RenderPartial this view within the UpdateTargetId div in another, containing view.

This way you can return the viewmodel with the model errors when you have them, or else just show some success message of your choice (if any). here is a great, detailed explanation: http://xhalent.wordpress.com/2011/02/05/using-unobtrusive-ajax-forms-in-asp-net-mvc3/
