Hi Steve,
Unfortunately, it is not possible to use a Detached CommandBar with a ChildFrameBarManager. However, you could add a Detached CommandBar to the parent form and have the control use the ActiveMDIChild property of the form to direct the input to the appropriate child. However, you''ll have to control the visibility of the CommandBar yourself.
I have attached a
sample that demonstrates this.
