I can't figure out how to make a TaskpaneView I've created the active, focused, item.

ISldWorks.ActivateTaskPane(int) will let me focus the out of the box Taskpanes, defined in swTaskPaneTab_e.  But while I have a reference to the TaskpaneView I've created with CreateTaskpanView3 I can't connect the dots.

Is there no way for me to have a CommandItem's CallbackFunction bring my custom TaskpaneView into
