I recently discovered CompositeCommand and find it works great for this scenario. It's part of Prism, but I just ripped it out since I don't use Prism.

https://prism.svn.codeplex.com/svn/V1/spikes/AGCompositeApplicationLibrary/AGComposite.Wpf/Commands/CompositeCommand.cs[^]

The toolbar will bind to a static CompositeCommand (i.e. in something like a GlobalCommands.cs) and then a view would attach to it with a RelayCommand. Something like:

GlobalCommands.SaveCommand.RegisterCommand(SaveCommand);

Multiple views can attach to the same command and all get notified when the button is clicked. The one gotcha though is the IActiveAware portion. Your ViewModelBase class needs to be tweaked to properly set the IsActive flags in the commands somehow.

Basically the way the CompositeCommand works is that say vmA and vmB attach... by default, the button will only enable if both return true for canExecute. By setting the IsActive flag on the commands properly, you can make it work in a way where the inactive commands are ignored. For example, if vmA.SaveCommand is not active, only vmB.SaveCommand will get the canexecute/execute calls.
