Composite Application Guidance for WPF & Silverlight (Prism-v2) Reference Implementation using Silverlight 3 Validation2 Comments

A different approach to reduce code behind through attached behaviors in the views can be used to keep a list of the validation errors. This blog post provides more information about it.
After all the changes were made, the following is the outcome with invalid data input:
