Hi Greg,
You should have different instance of the GridControl in each tabpage. But you can have the same GridModel (that holds all the data information) for all these GridControl instances. When you make any changes in one GridControl, the changes will be reflected in other GridControl in other tabpages.
Please refer to the attached sample and let me know if this helps you. Thanks for using Essential Tools.
Regards,
Mano
