This enumeration is used by a property within the ValueSource structure, which in turn is obtained by calling a GetValueSource method against a particular dependency property.

Each value of this enumeration indicates that a particular aspect of the overall WPF property system was responsible for the effective value determination of a certain dependency property value on a specific dependency object. To learn more about the WPF property system and the precedence at which each aspect of the property system operates, see Dependency Property Value Precedence.

The value Default is not the default value of the enumeration.
