Thank you for writing back.
You can control whether the newly added document will be added in front or to the back of the tabbed documents by the DocumentManager.DocumentInsertOrder
property. It is necessary to set it to DockWindowInsertOrder.ToBack
and thus the new documents will be added to the back.
.radDock1.DocumentManager.DocumentInsertOrder = DockWindowInsertOrder.ToBack;
I hope this information helps. If you have any additional questions, please let me know.
