Validation in WinRT XAML apps Not built in Bindings have no notion of validation Controls have no built in rendering for errors Need to build your own Validation should: Not annoy the user until they have done something wrong Be checked when properties change Allow rules to be defined in a standardized way Including System.ComponentModel.DataAnnotations Support rules attached to Model or ViewModel properties Support displaying errors to the user at the field level or in summary form

Prism validation support BindableValidator Manages a collection of errors per property for a data object Raises events when the errors change to support data binding Can evaluate DataAnnotations automatically ValidatableBindableBase Derives from BindableBase Contains a BindableValidator Exposes errors for data binding Triggers validation when properties change HighlightXYZOnErrors behaviors Attached behaviors to show a red box on control when there are errors associated with the bound property
