Stephen,

Check out DynamicBackColor, the examples in the help are pretty clear, but here is what you keep in mind:

1. DynamicBackColor is a property of the columns of the grid
2. Because of point 1, you assign (in this case) the same expressions to all columns.
3. Most folks get the effect you want here by storing the record number of the current record, and then using an IIF() in the DynamicBackColor to assign one color to the current record, and another color to the others.

Hope this helps.
