Silverlight and RIA Services are great technologies and the Model-View-ViewModel (M-V-VM) pattern is a nice approach to keep UI and logic separated. But using the combination of view models with item controls, dataforms and commands can be a laborious task because the databinding features in Silverlight are quite limited. I posted an article on my website in which I demonstrate how binding with ViewModels can be improved by using the BindingHelper class and by creating your own command behaviors.
