Вот выдрал из примера, сам не разбирался, может чем-то поможет.
function TCustomDrawDemoMainForm.DrawCellItem(AItem: TcxItemCustomDrawInfo;
ACanvas: TcxCanvas; AValueInfo: TcxRowValueInfo; APainter: TcxvgPainter;
Sender: TObject): Boolean;
procedure OwnerDrawText(ALineColor: TColor; AFont: TFont);
var
ARect: TRect;
begin
ACanvas.Pen.Color := ALineColor;
ACanvas.Brush.Style := bsClear;
ACanvas.Font := AFont;
ARect := cxRectInflate(AValueInfo.BoundsRect, -1, 0, 0, -1);
with ARect do
ACanvas.Canvas.Rectangle(Left, Top, Right, Bottom);
if AValueInfo.EditViewInfo is TcxCustomCheckBoxViewInfo then
with TcxCustomCheckBoxViewInfo(AValueInfo.EditViewInfo) do
AValueInfo.LookAndFeelPainterClass.DrawCheckButton(ACanvas,
cxRectOffset(CheckBoxRect, AValueInfo.BoundsRect.Left, AValueInfo.BoundsRect.Top),
cxbsDefault, State = cbsChecked)
else
if AValueInfo.EditViewInfo is TcxCustomTextEditViewInfo then
with TcxCustomTextEditViewInfo(AValueInfo.EditViewInfo) do
ACanvas.DrawTexT(Text, cxRectInflate(AValueInfo.BoundsRect, -2, -2), 0);
end;
var
AStyle: TcxStyle;
begin
TcxVerticalGrid(Sender).ViewInfo.LinesInfo.Clear;
AValueInfo.Transparent := (AValueInfo.ViewParams.Bitmap <> nil) and
(not AValueInfo.ViewParams.Bitmap.Empty);
if AItem.DrawingStyle = cdsDefaultDrawing then
begin
APainter.DrawRowValueCell(AValueInfo);
DrawCellsLines(ACanvas, TcxVerticalGrid(Sender).OptionsView.GridLineColor, AValueInfo.BoundsRect);
DrawRightLine(ACanvas, TcxVerticalGrid(Sender).OptionsView.GridLineColor, AValueInfo.BoundsRect);
Result := True;
Exit;
end;
if AItem.DrawingStyle = cdsDependsOnData then
begin
if cxDBVerticalGridCustomer.Properties.Values[AValueInfo.RecordIndex] = 'Y' then
AStyle := CustomDrawDemoDataDM.stCustomer
else
AStyle := CustomDrawDemoDataDM.stNoCustomer;
ACanvas.Brush.Color := AStyle.Color;
