WPF tasarımının bir bölümünü birden çok pencere için ortak hale getirme

bu yüzden bu Visual Basic WPF'Yİ yapıyorum ve birden çok pencere arasında ortak olacak bir gezinme çubuğum var ve yalnızca bu gezinme çubuğu için bir XAML ve sınıf oluşturmanın bir yolu olup olmadığını merak ediyordum ve sonra diğer pencerelere aktarıyorum, böylece her yeni pencere oluşturduğumda aynı kodu kopyalayıp yapıştırmam gerekmiyor.

Geçerli kod:

Ana pencere.vb

Class FloorWindow
    Private Sub SetAllInactive()
        ' This function will change all StackPanel objects
        ' of the navGrid to its inactive style which consists
        ' of opacity .1

        Dim childType As String

        For Each child In navGrid.Children
            childType = child.GetType().ToString()
            ' Check if child object of navGrid is a StackPanel
            If childType = "System.Windows.Controls.StackPanel" Then
                child.Opacity = 0.1
            End If
        Next
    End Sub
    Private Sub LogoBtnClick(sender As Object, e As RoutedEventArgs) Handles logoBtn.Click
        Trace.WriteLine("Logo Clicked")
        ' Go to default page
        SetAllInactive()
        floorStack.Opacity = 1
    End Sub

    Private Sub FloorBtnClick(sender As Object, e As RoutedEventArgs) Handles floorBtn.Click
        Trace.WriteLine("Floor Clicked")
        ' Go to floor page and change its stack to active attributes
        SetAllInactive()
        floorStack.Opacity = 1
    End Sub

    Private Sub ClientsBtnClick(sender As Object, e As RoutedEventArgs) Handles clientsBtn.Click
        Trace.WriteLine("Clients Clicked")
        ' Go to floor page and change its stack to active attributes
        SetAllInactive()
        clientsStack.Opacity = 1
    End Sub

    Private Sub SettingsBtnClick(sender As Object, e As RoutedEventArgs) Handles settingsBtn.Click
        Trace.WriteLine("Settings Clicked")
        ' Go to floor page and change its stack to active attributes
        SetAllInactive()
        settingsStack.Opacity = 1
    End Sub
End Class
