I have a table for which I am creating and substituting various datasets. The Table itself is working great - now I am trying to find a way of sending new values to the OPC tags that are used to fill the various datasets through a pop-out window that originates from clicking the table.

So basically what I would like to do :

OPC Tag —\>Dataset —\> Table (for display) —\>Pop-out (to edit)  
-------\<---------\<---------------------\<-------------------------------\<-------

I am looking for someway to extract the OPC address from the dataset if that is even possible.

we save the tagpath in a hidden column on the table.

I was considering that as an option, making an entire dataset of nothing but tag paths.

It might be difficult with just an invisible row because each cell has a different tag path, but that is a good idea thank you!
