Ok, the "persistent data" of your datagrids should be set to false.

Because the dgs are empty when you first open the card, we can assume
that the "lag" is not due to the amount of rows.

Assuming that your dgs are filled after you unlock the messages, you
have no risk. Because the first time you open the card by blocking the
messages, the dgs are not initialized, but as soon as you fill the
data in the dgs, the initialization stuff is executed (this stuff is
executed by setting the dgData prop of dgs which have not been
initialized previously)

Anyway, you should not have this kind of "lag" with initialization of
empty dgs (more than 2 seconds??).
Assuming the dgs are empty, that is not something located in the row
behavior (the dgs are empty so they not require to use the layout or
fillindata messages) or with the number of controls in a template:
nothing is drawn.
Maybe something in the code of a dg group or assuming you have custom
sorting, in a header behavior.

If you want, I could have a look to your dgs.
