Ideal varies from person to person in this standards-less industry.

If you were using an n-tier design to grab your data - the answer to this would be a no-brainer. You'd alter the query populating this grid to join to the company table and grab the name. Then you set the controlsource to show the company name.

I hope that points you in a helpful direction.
