Ich habe versucht, einige Steuerungsvorlagen oder Lösungen für dieses Problem im Internet zu finden, aber ich habe keine „akzeptable“ Lösung für mich gefunden. Also habe ich es auf meine Weise geschrieben und hier ist ein Beispiel für meinen ersten (und letzten =)) Versuch, es zu tun:

Diese beiden Konverter habe ich geschrieben, um die Tab-Größe an den Inhalt anzupassen. Eigentlich mache ich Path Objekt abhängig von der Inhaltsgröße. Wenn Sie keine Registerkarten mit unterschiedlichen Breiten benötigen, können Sie eine modifizierte Kopie davon verwenden:
<Style x:Key="tabPath" TargetType="{x:Type Path}">
<Setter Property="Stroke" Value="Black"/>
<Setter Property="Data">
<Setter.Value>
<PathGeometry Figures="M 0,0 L 0,14 C 0,18 2,20 6,20 L 60,20 C 70,20 80,0 84,0"/>
</Setter.Value>
</Setter>
</Style>

Path.DataElement in der XAML verursacht wird. Wenn ich dieses Element auskommentiere, ist der Designer stabil. Haben Sie eine Ahnung, wie dieses Problem behoben werden könnte?
