wpf - 如何更改 WPF 框架中导航栏的属性？

Question

我正在开发一个基于页面的 WPF 应用程序，我想更改框架中导航栏的大小。我设置了 NavigationUIVisibility="Visible"以查看导航栏，现在如何更改导航栏上的属性，如它的大小？

谢谢，

导航栏很难改变。我建议您自己创建。
创建您自己的按钮，然后使用

myFrame.NavigationService.GoBack()
myFrame.NavigationService.GoForward()

例子:

Private Sub PreviousPageCommand_Executed(ByVal sender As Object, _
                                     ByVal e As ExecutedRoutedEventArgs)
    MainFrame.NavigationService.GoBack()
End Sub

Private Sub PreviousPageCommand_CanExecute(ByVal sender As Object, _
                            ByVal e As CanExecuteRoutedEventArgs)
    If Not MainFrame Is Nothing Then
        e.CanExecute = MainFrame.NavigationService.CanGoBack
    Else
        e.CanExecute = False
    End If
End Sub

Private Sub NextPageCommand_Executed(ByVal sender As Object, _
                                     ByVal e As ExecutedRoutedEventArgs)
    MainFrame.NavigationService.GoForward()
End Sub

Private Sub NextPageCommand_CanExecute(ByVal sender As Object, _
                                    ByVal e As CanExecuteRoutedEventArgs)
    If Not MainFrame Is Nothing Then
        e.CanExecute = MainFrame.NavigationService.CanGoForward
    Else
        e.CanExecute = False
    End If
End Sub
