FrameworkPropertyMetadata.Journal Property

Definition

Namespace:

System.Windows

Assembly:

PresentationFramework.dll

Gets or sets a value that indicates whether this property contains journaling information that applications can or should store as part of a journaling implementation.

public:
 property bool Journal { bool get(); void set(bool value); };

public bool Journal { get; set; }

member this.Journal : bool with get, set

Public Property Journal As Boolean

Property Value

Boolean

true if journaling should be performed on the dependency property that this metadata is applied to; otherwise, false. The default is false.

Exceptions

InvalidOperationException

The metadata has already been applied to a dependency property operation, so that metadata is sealed and properties of the metadata cannot be set.

Remarks

Properties on derived classes of PropertyMetadata are typically defined in the object model as read-write. This is so they can be adjusted after initialization of the instance. However, after the metadata is consumed as part of a call to Register, AddOwner, or OverrideMetadata, the property system will seal that metadata instance and properties that convey the specifics of the metadata are now considered immutable. Attempting to set this property after IsSealed is true on this metadata instance will raise an exception.

XAML Text Usage

Members of this class are not typically used in XAML.
