How does the ViewModel know which object in the collection has the error? Very confusing and I dont see the "light" at the end of the tunnel on this approach on a bound datagrid?

What about running validation when a user clicks on the button and only continue if there are no validation errors?

Cheers,

This means User can directly press Calculate button & the input will not be validated. How can i validate all 'Not Set' properties automatically when User clicks on the button?Thanks!

As you’re an developer with 10 years experience I would be interested to know if you understand why for some folks, including me this is a step forward.

If you want a clue think about testability.

As an asp.net dev, for the last 10 years, I have been doing validation on my forms in about 10 minutes by simply dragging some validation controls on the screen and setting some properties. This much coding for some simple validation seems like a huge step backwards. This is nice but an insane amount of code for validation.
