Hi Megabyzus,

As I said in previous posts you can choose between various implementation options, but in general I think that COMMAND mode is to be preferred in this scenario.
In fact, this mode allows you to automatically keep updated all the clients with the changes in the list of items to be displayed.
Please consider this scenario where each client can autonomously make changes to the grid, also to add or remove a row, and communicate these changes to the adapter through for example a sendmessage.
At this point the adapter processes the changes, updates its internal state and produces the proper commands (in terms of ADD, DELETE, or UPDATE) to be forwarded in order to synchronize all the other clients.

Please let me know if this is something applicable to your use case.

Regards,
Giuseppe
