How do I record selecting first row of datagrid (dynamic values)?

I have successfully recorded the selecting of a datagrid row.

But the data is dynamic (db driven), thus becomes different from what was there when I recorded the click.
Next time, that row no longer exists, the step fails, a domino effect entails, dependant steps also fail.

How to I configure a 'click' or 'select' step to me smarter / refer to programatic names of elements being clicked on?
When I tried to enter code values in the properties fields of that step (Target value, Arguments, etc.), it threw errors.

Help??

Thanks,
