You may also find the Validation Application Block (which is part of the Enterprise Library Silverlight Integration Pack) useful. It's in public preview right now.

I wrote my own validaion for SL2. It's based on:

  1. Attached property to give control custom validation ID
  2. Business object validators that identify invalid data
  3. VisualTreeHelper to parse visual tree and match validation result and custom validation ID
  4. Custom templates for controls in order to display validation
  5. INotifyPropertyChanged to remove validation display if property value was changed.

If you're using Silverlight 3 check out Data Validation. http://www.silverlightshow.net/items/Data-Validation-in-Silverlight-3.aspx

If you're using Silverlight 2 you'll have to roll your own code for validation.
