Как сделать некоторую часть дизайна WPF общей для нескольких окон

итак, я создаю этот Visual Basic WPF, и у меня есть панель навигации, которая будет общей для нескольких окон, и мне было интересно, есть ли способ создать XAML и класс только для этой панели навигации, а затем импортировать его в другие окна, чтобы мне не приходилось копировать и вставлять один и тот же код каждый раз, когда я создаю новое окно.

Текущий код:

Главное окно.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
