I am not getting why this is happening. Any idea…see xaml below this error message

  1. I’ve tested your code inside VS2008 with .NET 3.5 SP1 and if i remove declaration for TrinityDeviceTree it works fine with the designer. Maybe you should chek upon that UserControl and look there for errors. Also try to make a clean of your project and a rebuild, sometimes it works for visual designer’s issues.
