Defines members that data entity classes can implement to provide custom synchronous and asynchronous validation support.
See Also: INotifyDataErrorInfo
This 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.
Assembly: System (in System.dll)
