Prevent Save when Validation Errors occur on WPF DataGrid

Question

Currently, I have a DataGrid which is bound to some data in my ViewModel. I have ValidationRules set up for the Rows, and the Columns. What I would like to do is prevent the user from saving the file if there are any Validation Errors. I am using the RelayCommands class to route the Open, Save, etc commands to my ViewModel.

You might be interested in the BookLibrary sample application of the WPF Application Framework (WAF). It disables the Save button when a validation error is active (e.g. DataGrid).
