Namespace: DevExpress.Xpf.WindowsUI.Navigation
Assembly: DevExpress.Xpf.Controls.v23.2.dll
NuGet Package: DevExpress.Wpf.Controls
Declaration
Property Value
| Type | Description |
|---|---|
| IEnumerable<JournalEntry> | An IEnumerable that stores JournalEntry objects. |
Remarks
Each time an end-user navigates forward to a View within a WindowsUI application, the previous View is written to a JournalEntry object and placed to the BackStack collection. This allows you to call the Journal.GoBack method and sequentially navigate back to previously displayed Views.
If the BackStack collection contains more than 1 entry (its first entry always corresponds to the NavigationFrame.Source View), the Journal.CanGoBack property returns true.
Calling the Journal.GoBack and Journal.GoHome methods decrements the BackStack collection and increments the Journal.ForwardStack collection respectively.
