Check out <http://lessons.runrev.com/spaces/lessons/manuals/datagrid/lessons/7340-What-Sorts-of-Things-Should-I-Not-Do-In-Order-To-Avoid-Needless-Suffering->.

One of the paragraphs says:

Don't try to draw a Data Grid on a card that Is not open
When a Data Grid renders it dynamically creates fields and accesses
certain properties. Some of these properties can not be properly
reported by the Revolution engine unless the field is on an open card.

So basically, you can't do what you have in mind.
Would it work to lock the screen, go to the second card, draw the DG
and then go back to where you were?
