In this posting I’ll extend the data validation mechanism we’ve been examining to support asynchronous data validation.Silverlight is all about client-side code, and client-side validation is often exactly what you want; however there are times that you do not want to expose your validation algorithm in the client or in which you need to do a dynamic database lookup (credit ratings come to mind). In that case, you’ll want your Silverlight application to be able to validate against a web service, but to keep working while it does so. That’s just what we’ll do today.
