Or only on the server in the controller/function that matches the link? If on the server, doesn't the db query for the row selected give that value? If on the client, you would be looking at picking up the proper td entry. I don't have a grid example going at the moment. I have an SQLTABLE example that doesn't seem to name anything in the table (unlike an SQLFORM where everything is named). But for a grid, aren't you intercepting a click on the link inside a td, and the other td would just be one of its siblings? /dps -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
