Multiple Command Bars on Form with Docking Panes

I am having great difficulty adding multiple command bars to a form to create a visual studio style interface.  A form that contains two docked side panes.  Each pane has its own command bar (docked at the top)

I originally approached this by using forms for the docking panes which worked but caused me a number of issues, one pressing enter in a command bar text control (on the docking pane) caused events to be fired in the main form (eg key up on a report control).  It was as like all forms where actively receiving events at the same time.  Two I couldn’t tab between the controls.

After reading a number of posts I switched to using picture boxes instead of forms for the docking panes.  This now behaves how I want it to.  Now I have the problem of re-implementing the command bars, docked at the top of each pane.

Does anyone have any ideas how I can achieve this?

I cannot attach an individual command bar to a picture box as it appears that the AttachToWindow Sub is only available on the collection of command bars and is not available for each command bar.

I tried adding multiple command bar controls to the form but this caused them to stop working.

Has anyone managed to add more than one command bar control to a form?  If so, how?

Sorry for the long winded post.   Thanks in advance.
