Specifies whether a Frame uses its own journal. JournalOwnership is used by the JournalOwnership property.
public enum class JournalOwnership[System.Serializable]
public enum JournalOwnershippublic enum JournalOwnership[<System.Serializable>]
type JournalOwnership = type JournalOwnership = Public Enum JournalOwnership- Inheritance
- Attributes
Fields
| Name | Value | Description |
|---|---|---|
| Automatic | 0 | Whether or not this Frame will create and use its own journal depends on its parent. |
| OwnsJournal | 1 | The Frame maintains its own journal. |
| UsesParentJournal | 2 | The Frame uses the journal of the next available navigation host up the content tree, if available. Otherwise, navigation history is not maintained for the Frame. |
Examples
The following example illustrates a Frame yielding journal management to a host NavigationWindow.
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
<!-- Frame that uses its own journal -->
<Frame JournalOwnership="OwnsJournal" Source="Page2.xaml" />
</Page>
Remarks
When JournalOwnership is Automatic, the following behavior applies:
The hosted Frame behaves as though UsesParentJournal was set if it is hosted by either a Frame or a NavigationWindow.
The hosted Frame behaves as though OwnsJournal was set if:
It is not directly hosted by either a Frame or NavigationWindow.
It is hosted by at least one Frame, where each containing Frame has its JournalOwnership property is set to UsesParentJournal.
Note
once a Frame creates its own journal, switching to Automatic has no effect.
