Free SilverlightShow Webinar: WCF RIA Services Validation
March 16th, 2011, 10 am - 11.10 am PDT (see your local time)
Register for this webinar
Brian Noyes continues his series of Silverlight Show webinars covering his very successful article series on WCF RIA Services. In this session Brian will dive in depth into the validation features of WCF RIA Services. You will see how to leverage WCF RIA Services validation mechanisms when editing data with validation that is part of the entities, server side validation when updates occur, and asynchronous validation on the server from the client.
This session will step you through the process of defining your entities so that they can validate input data both on the client side and server side using data annotation attributes. They get evaluated on the client side and can be used to prevent even sending invalid data to the server side, but are also validated on the server side as well in case non-RIA Services clients are calling your services.
You’ll see how to address validations that require server side lookups, returning exceptions that get automatically associated with the respective entity so that it displays validation errors when in an editable control in Silverlight. You’ll also see how to use [Invoke] methods in a RIA Service to do asynchronous validation from the client using server side rules.
The live session includes a short Q&A part at the end. A recording of this session will be emailed to all registrants.
