The CogDataBinding type exposes the following members.

Constructors

	Name	Description
	CogDataBinding(SerializationInfo, StreamingContext)	Initializes a new instance of the CogDataBinding class with serialized data.
	CogDataBinding(Object, String, Object, String)	Constructs a new instance of the CogDataBinding class.
	CogDataBinding(Object, String, Object, String, Boolean)	Constructs a new instance of the CogDataBinding class.

Methods

	Name	Description
	BindTo	Redirects the binding to a new source and path.
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Dispose	Frees all resources used by the CogDataBinding and removes it from its container.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	FindDataBindings	Gets an array of all data bindings bound to a property of the supplied object. Data bindings having complex paths in which any portion reference the source object, are also included in the array.
	GetAttributes	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetClassName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetCompatibleOutputs(Type, Object)	Gets a list of all output properties that can be assigned to the given type.
	GetCompatibleOutputs(Type, Type)	Gets a list of all output properties that can be assigned to the given type. This override should only be called if an instance of the source object is not available.
	GetComponentName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetConverter	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultEvent	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultProperty	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEditor	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetObjectData	Implements the GetObjectData method of the ISerializable interface. (Inherited from CogSerializableObjectBase.)
	GetProperties	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetProperties( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetPropertyOwner	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetSourceValue	Reads the current value of the source property. May throw an exception if the source property is not currently valid.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	OnChanged(Int64)	This method should be called internally whenever the object's state may have changed. (Inherited from CogSerializableChangedEventBase.)
	OnChanged(CogChangedEventArgs)	This method may be called internally whenever a derived object's state may have changed and the derived object expresses this change via a derived CogChangedEventArgs class. (Inherited from CogSerializableChangedEventBase.)
	OnDeserialization
	RefreshBinding	Refreshes the destination property from the source
	ResumeAndRaiseChangedEvent	Re-enables raising of the Changed event after SuspendChangedEvent has been called, and raises the Changed event if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent. (Inherited from CogSerializableChangedEventBase.)
	SuspendChangedEvent	Temporarily suspends the raising of the Changed event. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent. (Inherited from CogSerializableChangedEventBase.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Fields

	Name	Description
	SfContainer	State flag for the Container property.
	SfNextSf	Next state flag to be used in derived classes.
	SfOptimizeIneffectiveChanges	State flag for the OptimizeIneffectiveChanges property.
	SfSource	State flag for the Source property.
	SfSourcePath	State flag for the SourcePath property.
	SfSourceProperty	State flag for the SourceProperty property.
	SfUpdateException	State flag for the UpdateException property.
	UpdateException_	Exception thrown when the binding tried to update its value.

Properties

	Name	Description
	ChangedEventSuspended	If nonzero, indicates that the raising of the Changed event has been suspended. This value is incremented when SuspendChangedEvent is called and decremented when ResumeAndRaiseChangedEvent is called. (Inherited from CogSerializableChangedEventBase.)
	Container	Returns the collection that contains the binding.
	Destination	Gets the destination object.
	DestinationPath	Gets the destination property name or dotted property path.
	DestinationProperty	Gets a PropertyDescriptor for the destination property.
	HasChanged	(Inherited from CogSerializableChangedEventBase.)
	OptimizeIneffectiveChanges	Determines if this data binding will optimize out any attempts to set the destination property to its current value.
	Source	Gets the source object.
	SourcePath	Gets the source property name or dotted property path.
	SourceProperty	Gets a PropertyDescriptor for the source property.
	StateFlags	Returns the complete set of state flags supported on this object. The flags may be indexed by name as shown in the following C# code snippet: if (changedObject.StateFlags["Color"] & eventArgs.StateFlags) { ... } (Inherited from CogSerializableChangedEventBase.)
	UpdateException	Gets the exception, if any, that was thrown when the binding attempted to update its property value from its DataSource.

Events

	Name	Description
	Changed	This event is raised when one or more parts of the object's state may have changed. (Inherited from CogSerializableChangedEventBase.)
