Public Methods

Method	Description
CleanUp ( ) : void	Cleans up the information by unsubscribing from all events.
ClearDefaultErrors ( string propertyName ) : void	Updates the default errors. This method is required when errors are initialize via InitializeDefaultErrors. This method checks whether default errors were added for a specific property (or at entity level if propertyName is string.Empty or `null`). Reason for this is that if the error is known on forehand, the entity implementation will not raise the INotifyDataErrorInfo.ErrorsChanged event. If the default errors are cleared, the validation via INotifyDataErrorInfo.ErrorsChanged will take over from this point.
GetErrors ( string propertyName ) : IEnumerable	Gets the errors for the specificied propertyName. If the propertyName is `null` or string.Empty, entity level errors will be returned.
GetWarnings ( string propertyName ) : IEnumerable	Gets the warnings for the specificied propertyName. If the propertyName is `null` or string.Empty, entity level warnings will be returned.
InitializeDefaultErrors ( IEnumerable validationResults ) : void	Initializes the default errors.
ModelErrorInfo ( object model ) : System	Initializes a new instance of the ModelErrorInfo class.

GetValidationString ( object obj ) : string	Gets the validation string from the object. This method supports the following types: * string * ValidationResult
HandleBusinessRuleErrors ( IEnumerable errors ) : void	Handles the business rule errors.
HandleBusinessRuleWarnings ( IEnumerable warnings ) : void	Handles the business rule warnings.
HandleFieldErrors ( string propertyName, IEnumerable errors ) : void	Handles the field errors.
