Silverlight 3 and ValidationScope

if you are still stuck on Silverlight 3 as some of our projects are then most of the input controls take advantage of the Silverlight 3 Validation that depends on exceptions being thrown in Setter method in the domain object when a binding occurs. The exeception will result in Silverlight displaying the familar red box around the UI element. However this only solves part of the problem as the user can click on a some action button like Save without entering anything in the required input fields and of course the validation being setter based is not called. ValidationScope can help out here Josh Twist has a great blog posting at
