public interface class INotifyDataErrorInfopublic interface INotifyDataErrorInfotype INotifyDataErrorInfo = interfacePublic Interface INotifyDataErrorInfoThis interface enables data entity classes to implement custom validation rules and expose validation results asynchronously. This interface also supports custom error objects, multiple errors per property, cross-property errors, and entity-level errors. Cross-property errors are errors that affect multiple properties. You can associate these errors with one or all of the affected properties, or you can treat them as entity-level errors. Entity-level errors are errors that either affect multiple properties or affect the entire entity without affecting a particular property.
