Adding a textblock to a custom wpf control (piepiece control from codeplex)

I'm currently building a Surface application where the main navigation is a circular menu. For each menu item I'm using a custom control that I found on codeproject.com:

http://www.codeproject.com/KB/WPF/PieChartDataBinding.aspx (PiePiece control)

The number of submenu items (which is also piepiece controls) comes from a database and thus dynamically loaded. What I can't figure out is how I add a textblock to this custom control to display the submenu item text. It needs to follow the PiePiece's RotationAngle property to line up correctly.

Anyone got a hot-fix for this? I was thinking about adding another dependencyproperty to the piepiece custom control, but that way I can't set the font-family, size etc (can I?)

Any input on this is greatly appreciated! Thanks!

Have you tried using an Adorners, without taking a really close look the PiePiece Control you're using this might solve your problem.

Hope that helps!
