Public Methods

Method	Description
Equals ( object obj ) : bool	Determines whether the specified System.Object is equal to this instance.
GetHashCode ( ) : int	Returns a hash code for this instance.
SuspendChangeCallbacks ( ) : IDisposable	Suspends the change callbacks whenever a property has been called. This is very useful when there are expensive property change callbacks registered with a property that need to be temporarily disabled.
SuspendChangeNotifications ( bool raiseOnResume = true ) : IDisposable	Suspends the change notifications until the disposed object has been released.
SuspendValidations ( bool validateOnResume = true ) : IDisposable	Suspends the validation until the disposable token has been disposed.
ToString ( ) : string	Returns a System.String that represents this instance.
Validate ( bool force, bool validateDataAnnotations ) : void	Validates the current object for field and business rule errors. To check whether this object contains any errors, use the INotifyDataErrorInfo.HasErrors property.
operator ( ) : bool	Implements the operator ==.

Protected Methods

Method	Description
ClearIsDirtyOnAllChilds ( ) : void	Clears the IsDirty on all childs.
GetBusinessRuleErrors ( ) : string	Gets the current errors errors.
GetBusinessRuleWarnings ( ) : string	Gets the current business warnings.
GetFieldErrors ( string columnName ) : string	Gets the errors for a specific column.
GetFieldWarnings ( string columnName ) : string	Gets the warnings for a specific column.
InitializeCustomProperties ( ) : void	Allows the initialization of custom properties. This is a virtual method that is called inside the constructor before the object is fully constructed. This might be considered as bad or as a hack, but it's a good way to be able to inject custom properties before any actual logic is handled by derived classes. Only use when you really know what you are doing.
ModelBase ( SerializationInfo info, StreamingContext context ) : Catel.IoC	Initializes a new instance of the ModelBase class. Only constructor for the ModelBase. Call this method, even when constructing the object for the first time (thus not deserializing).
NotifyValidationResult ( IValidationResult validationResult, bool notifyGlobal ) : void	Raises the right events based on the validation result.
OnBeginEdit ( System.ComponentModel.BeginEditEventArgs e ) : void	Raises the IEditableObject.BeginEdit event.
OnCancelEdit ( System.ComponentModel.EditEventArgs e ) : void	Raises the IEditableObject.CancelEdit event.
OnCancelEditCompleted ( System.ComponentModel.CancelEditCompletedEventArgs e ) : void	Raises the IAdvancedEditableObject.CancelEditingCompleted event.
OnEndEdit ( System.ComponentModel.EditEventArgs e ) : void	Raises the IEditableObject.EndEdit event.
OnInitialized ( ) : void	Called when the object is initialized.
OnInitializing ( ) : void	Called when the object is being initialized.
OnPropertyObjectCollectionChanged ( object sender, NotifyCollectionChangedEventArgs e ) : void	Called when a property that implements INotifyCollectionChanged raises the event.
OnPropertyObjectCollectionItemPropertyChanged ( object sender, PropertyChangedEventArgs e ) : void	Called when a property inside a collection that implements INotifyCollectionChanged that implements INotifyPropertyChanged raises the event.
OnPropertyObjectPropertyChanged ( object sender, PropertyChangedEventArgs e ) : void	Called when a property that implements INotifyPropertyChanged raises the event.
OnValidated ( IValidationContext validationContext ) : void	Called when the object is validated.

OnValidatingBusinessRules ( IValidationContext validationContext ) : void	Called when the object is validating the business rules.
OnValidatingFields ( IValidationContext validationContext ) : void	Called when the object is validating the fields.
RaisePropertyChanged ( object sender, Catel.Data.AdvancedPropertyChangedEventArgs e ) : void	Raises the INotifyPropertyChanged.PropertyChanged event. This method is overriden en does not call the base because lots of additional logic is added in this class. The RaisePropertyChanged(object,System.ComponentModel.PropertyChangedEventArgs,bool,bool) will explicitly call ObservableObject.RaisePropertyChanged(object, AdvancedPropertyChangedEventArgs). If this method is overriden, it is very important to call the base.
SetDirtyAndAutomaticallyValidate ( string propertyName, bool setDirtyAndAllowAutomaticValidation ) : void	Sets the IsDirty property and automatically validate if required.
SetParent ( IParent parent ) : void	Sets the new parent of this object.
ShouldPropertyChangeUpdateIsDirty ( string propertyName ) : bool	Determines whether a specific property change should update `IsDirty` to `true`.
Validate ( bool force = false ) : void	Validates the current object for field and business rule errors. To check whether this object contains any errors, use the INotifyDataErrorInfo.HasErrors property.
ValidateBusinessRules ( List validationResults ) : void	Validates the business rules of this object. Override this method to enable validation of business rules.
ValidateFields ( List validationResults ) : void	Validates the field values of this object. Override this method to enable validation of field values.

INotifyDataWarningInfo ( string propertyName ) : IEnumerable	Gets the warnings for the specific property name.
IXmlSerializable ( ) : XmlSchema	This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the T:System.Xml.Serialization.XmlSchemaProviderAttribute to the class.
IXmlSerializable ( XmlReader reader ) : void	Generates an object from its XML representation.
IXmlSerializable ( XmlWriter writer ) : void	Converts an object into its XML representation.

RaisePropertyChangedForAllRegisteredProperties ( ) : void	Invokes the property changed for all registered properties. Using this method does not set the IsDirty property to `true`, nor will it cause the object to validate itself automatically, even when the AutomaticallyValidateOnPropertyChanged is set to `true`.
