cxdbgrid根据字段值设置颜色

假设cxgrid为cxMain,TableView为ViewSelData,现在要根据数据集的colColorMark来改变本行的颜色,则可在ViewSelData的OnCustomDrawCell写入
if AViewInfo.RecordViewInfo.GridRecord.Values[colColorMark.Index] = null then   Exit;
case AViewInfo.RecordViewInfo.GridRecord.Values[colColorMark.Index] of
  1: ACanvas.Brush.Color := $FF0080;
  2: ACanvas.Brush.Color := $C0C0C0;
  3: ACanvas.Brush.Color := $FFFF80;
  4: ACanvas.Brush.Color := $ABAF8F;
  5: ACanvas.Brush.Color := $CA31CE;
  6: ACanvas.Brush.Color := $E6E8D7;
end;
