Currently, there are no property settings to control this, so you do have to do this from code.
The most straight-forward way is in prepareViewStyleInfo setting e.Style.backColor based on the value of e.RowIndex.
Private Sub GridDataBoundGrid1_PrepareViewStyleInfo(ByVal sender As Object, ByVal e As GridPrepareViewStyleInfoEventArgs) Handles GridDataBoundGrid1.PrepareViewStyleInfo
If e.RowIndex > 0 And e.RowIndex Mod 2 = 1 And e.ColIndex > 0 Then
e.Style.BackColor = Color.LightGreen
ElseIf e.RowIndex > 0 And e.ColIndex > 0 Then
e.Style.BackColor = Color.White
End If
End Sub
