Currently I am struggling having an Dockpanel inside a C# User Control Library because handling the MDI state is troublesome or not even possible...
Thus my question: is it even possible to have a MDI container inside another MDI container using Dockpanel-Suite? The best would be if the inner MDI container could be shipped as a shared library (This should be a User Control, shouldn't it?).
I solved the requirement using DocumentStyle.DockingMdi in the outer container and DocumentStyle.DockingWindow inside the inner container.
The result is fully functional but a bit ugly, so ... do not do it.
