I thought I knew how to do this, but..

I've got a form with a grid. I have a modal form ontop of it that is changing the record pointer (a find dialog). How can I get an any color to appear over the record I'm now on. How would I complete this code from the INIT of the Find Dialog:

This.oGrid.SetAll('DynamicBackColor','iif(lCurrentRecord,rgb(0,0,128),rgb(255,255,255))','Column')

And then I reset it unconditionally on destroy.
