Protected method NotifyRootValueChanged Raises the RootValueChanged event.
Protected method NotifySubPropertyChanged Raises the SubPropertyChanged event.
Protected method OnPropertyChanged(PropertyChangedEventArgs) Raises the PropertyChanged event with the specified PropertyChangedEventArgs.
Protected method OnPropertyChanged(String) Raises the PropertyChanged event with the specified string.
Protected method OnPropertyValueException Raises the PropertyValueException event.
Protected method SetValueCore When overridden in a derived class, sets the Value property to the specified Object.

Remarks

The PropertyValue class represents the underlying value of a property. The PropertyEntry class represents the property itself. The PropertyEntry is the parent, and the PropertyValue is the child.

If an instance of PropertyValue represents a value that is a collection, it uses the Collection property to return a PropertyValueCollection. An example of a property whose value is a collection is the RowDefinitions property.

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.
