This is the sixth of 8 videos by Ken Cox about the development of CRUD application using Silverlight and Visual Basic.NET.
In this episode, you build a XAML form that acts like a popup, modal window. The form validates user input with WCF callbacks to ensure that the customer ID is unique. By the end of the episode, you're able to add a customer to the NorthWind database using Silverlight, VB, ADO.NET Data Services and the Entity Framework. Here's a reminder: this series is sequential. If you haven't worked through the first five episodes, you'll find this one tough sledding because of the prerequisites.
Make sure you've worked through Episode 1, Episode 2, Episode 3, Episode 4 and Episode 5 first.
Sometimes the video might not be available because of some internal problems of the Silverlight streaming services. Please excuse us for the inconvience, we hope that this problem will be fixed very soon.
