Use this enumeration when you construct a FrameworkPropertyMetadata instance where you want to specify one or more the framework-level metadata option settings.

You no longer use this enumeration after the constructor call. Instead, query the particular metadata option that was set during registration by checking the true or false value of a specific property of an existing FrameworkPropertyMetadata. These property names match the FrameworkPropertyMetadataOptions enumeration values except for NotDataBindable, which is IsNotDataBindable on the finished FrameworkPropertyMetadata.

The Journal option only specifies the intention to be journaled. The actual journaling may or may not be addressed by journaling services such as those that are present in the WPF viewer application. In particular, journaling has some known limitations if the element tree was constructed through code rather than XAML. For details, see Navigation Overview.

Note:
Although property value inheritance might appear to work for nonattached dependency properties, the inheritance behavior for a nonattached property through certain element boundaries in the runtime tree is undefined. Always use RegisterAttached to register properties where you specify Inherits in the metadata.

The following example calls the FrameworkPropertyMetadata constructor, and sets several options by using values from the FrameworkPropertyMetadataOptions enumeration.

fpm = new FrameworkPropertyMetadata(
    Double.NaN,
    (FrameworkPropertyMetadataOptions.AffectsRender |
      FrameworkPropertyMetadataOptions.BindsTwoWayByDefault),
    new PropertyChangedCallback(OnCurrentReadingChanged),
    new CoerceValueCallback(CoerceCurrentReading)
);
