Here's basic code for current row highlight. It assumes that your grid class has property nRecNo.

* Grid Init
This.nRecNo = Recno(This.RecordSource)
This.SETALL("DynamicBackColor","IIF((THISFORM.nRecNo=RECNO(This.RecordSource))," + ;
   "RGB(0,0,255),RGB(255,255,255))","Column")
* Grid AfterRowColChange event
This.nRecNo = Recno(This.RecordSource)

>Now, I know there are a couple of ready made classes out there, but I'd like to try to do it myself.

>THIS.SETALL('DynamicBackColor','RGB(255,255,255)','Column')
>FOR i=1 TO THIS.COLUMNCOUNT
>   THIS.COLUMNS(i).CurrentControl.BackColor = 'RGB(192,192,192)'
