You can not do that with the designer, but as you add the Child of your ElementHost in code you can directly create and assign the ViewModel. As you commit changes on this ViewModel they get directly reflected in the WPF View.

MyView view = new MyView();
MyViewModel model = new MyViewModel();
view.DataContext = model;
ElementHost.Child = view;


model.SomeBoundProperty = somethingElse;
//Magic update of the WPF view
