Methods

	Name	Description
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Gets the value of a domain property for a specified element. (Inherited from DomainPropertyValueHandler<TElement, TValue>.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NotifyValueChange	Alerts listeners that the calculated value of a domain property has changed.
	OnValueChanged	Occurs after a property value has been changed. (Inherited from DomainPropertyValueHandler<TElement, TValue>.)
	OnValueChanging	Alerts listeners when a property value is about to change. (Inherited from DomainPropertyValueHandler<TElement, TValue>.)
	SetValue	Sets the value of a domain property for an element. (Overrides DomainPropertyValueHandler<TElement, TValue>.SetValue(TElement, TValue).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	ValueChanged	Adds a transaction record and raises the OnValueChanged event. (Inherited from DomainPropertyValueHandler<TElement, TValue>.)
	ValueChanging	Performs validation and raises the OnValueChanging event. (Inherited from DomainPropertyValueHandler<TElement, TValue>.)

Remarks

Each domain property that has a property value that is calculated has a CalculatedPropertyValueHandler<TElement, TValue>. CalculatedPropertyValueHandler<TElement, TValue> sets the value of the property and fires notifications when the property value changes.

These notifications are received by rules, events, and the OnValueChanging method.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
