C # WPF Custom Vertical TabControl Переполнение прокрутки

Question

Есть ли в сообществе кто-то, кто может мне помочь?

Вот вертикаль TabControl У меня так далеко:

<Window.Resources>
    <Style TargetType="{x:Type TabControl}">
        <Setter Property="OverridesDefaultStyle" Value="True" />
        <Setter Property="SnapsToDevicePixels" Value="True" />
        <Setter Property="Template">
            <Setter.Value>

И что я хотел бы получить, это, но работает:

                    SelectionChanged="MyTabControl_SelectionChanged"

Не стесняйтесь пролить свет на мои ошибки.
