It depends on whether you want to display data elements from a cursor or an array in your grid. If you write all the array elements to a cursor before hand, then your grid will be using the cursor as its recordsource. The fact that the cursor was populated from an array is something that's irrelevant at this point (the grid could care less). If you actually want to display the data directly from the array, then you need to set the controlsource to the individual array elements with the row subscript of the array mapped to your dummy cursor and the column subscript hard-coded so, no, you can't skip setting the controlsource.
