If you are using Silverlight 3, check Data Validation. http://www.silverlightshow.net/items/Data-Validation-in-Silverlight-3.aspx



If you are using Silverlight 2, you will need to copy your own code for validation.

I wrote my own validation for SL2. It is based on:



  • Bound property to give the user an individual control validation ID
  • Business object validators that identify invalid data
  • VisualTreeHelper to parse visual tree and compliance check result and custom check id
  • Custom templates for controls to display validation
  • INotifyPropertyChanged to remove the validation display if the property value has changed.

You can also find the Validator Application Block (which is part of the Silverlight Enterprise Library Integration Pack ). This is currently a public viewing.
