As stated in this question, it is possible to display the server-side validation errors inside the Data Form error summary with RIA Services. My question is, how can I do the exactly the same but this time with a "plain vanilla" (i.e. no RIA Services) Silverlight 3 setup?
Moreover, is it possible to highlight the Data Form fields that didn't validate as in the "Validating Data Update" section in Brad Abram's blog entry? How?
