Could you please support Event to Command in Prism? There are a few numbers of MVVM frameworks that support EventToCommand. Even we can copy the code or repeat the same thing in our own way, It would be the best if we have official support from Prism Framework.
One suggestion that I like to suggest for implementing Event to Command is that VM should have the reference to control. For example: If I'm using third-party control in View, but my view model shouldn't aware of that third-party control. The max scope of this third-party control should be only in View and attached property (not in ViewModel).
We will need a lot of tricks when it comes to usability. WPF strong binding is great and what Prism supports so far is also very good for developing WPF/Silverlight business application. But there are some scenarios that we need events (this is where Event to Command comes into picture.), setting focus or handling mouse or etc.
