Hi Larry,
Thank you for your interest in Syncfusion Products.
When you are docking the TabControlAdv using DockingManager, TabControlAdv with its TabPages, is docked to the Docking Manager as a single control. So it is not possible to dock each TabPageAdv and view its caption separatelty. If you need to display separate docking caption for each docking control, then we can tab more than one docking control and if we autohide it we can view each one's docking caption separately.
Please refer the sample given in the following link:
