How to: Navigate Back Through Navigation History

This example illustrates how to navigate to entries in back navigation history.

Example

Code that is running from content that is hosted in a NavigationWindow, Frame using NavigationService, or Internet Explorer can navigate back through navigation history, one entry at a time.

Navigating back one entry requires first checking that there are entries in back navigation history, by inspecting the CanGoBack property, before navigating back one entry, by calling the GoBack method. This is illustrated in the following example:

void navigateBackButton_Click(object sender, RoutedEventArgs e)
{
    // Navigate back one page from this page, if there is an entry
    // in back navigation history
    if (this.NavigationService.CanGoBack)
    {
        this.NavigationService.GoBack();
    }
    else
    {
        MessageBox.Show("No entries in back navigation history.");
    }
}

Private Sub navigateBackButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    ' Navigate back one page from this page, if there is an entry
    ' in back navigation history
    If Me.NavigationService.CanGoBack Then
        Me.NavigationService.GoBack()
    Else
        MessageBox.Show("No entries in back navigation history.")
    End If
End Sub

CanGoBack and GoBack are implemented by NavigationWindow, Frame, and NavigationService.
