Namespace: DevExpress.Xpf.WindowsUI.Navigation
Assembly: DevExpress.Xpf.Controls.v24.2.dll
NuGet Package: DevExpress.Wpf.Controls
Declaration
Property Value
Type | Description |
---|---|
Boolean | true, if a NavigationFrame related to the current Journal can navigate back; otherwise, false. |
Remarks
A Frame’s Journal stores all previously displayed Views in its Journal.BackStack and Journal.ForwardStack collections as JournalEntry objects. If the Journal.BackStack collection stores more than 1 entry, the CanGoBack property equals true and calling the Journal.GoBack or Journal.GoHome method will have an effect.
Note
The very first entry in the Journal.BackStack collection is a NavigationFrame‘s source View (see the NavigationFrame.Source property), from which you cannot navigate back.
