>I am trying to get this to work. The syntax works in another form, but on this one I keep getting the message "Expression is invalid. Use a valid expression for DYNAMICBACKCOLOR property." The strange this is that if I step through it, I don't get the message, only when it just runs. This code is in the AfterRowColChange event. vSbvPromoDestinations is a view, if that makes a difference. I am trying this because I have a few grids on the form, on one tab I have two grids, the lower being dependent on the upper. When swithcing between them, when I move the record pointer on the upper grid, the view controlling the other grid is requeried and the grid refreshed, but the record marker doesn't move. So I thought I'd get rid of it and use this.

Dana,
I think you already solved this. Anyway if not:
1) val(alltrim(THIS.tag)) - THIS is mandatory there. It's part of the expression. Error message is due to that.
2) Do "SetAll" once (anywhere - typical places are grid.init or form.init)
This is simple current row hihglighting. However you need a little touch for it to work right:

*Grid.BeforeRowColChange
lparameters nColIndex
thisform.LockScreen = .t.

*Grid.AfterRowColChange
lparameters nColIndex
this.Tag = str(recno())
thisform.LockScreen = .f.
