>Thanks to both of you, Larry & Stephen, for your help. I understand all of the comments so far, except what event to use (or where to place the code) to set the DynamicBackColor of all columns. I have tried different events of the grid with no success.

Hi Mark,
Christof Lange did a very thorough analysis of your problem a few months ago. I think it was in 'Ask Advisor'. It should answer all of your questions.
