如何让tcxGrid左边显示序号

第一步：

设置cxgrid的属性， optionsview.indicator = true

第二步：

写oncustomdrawindicatorcell方法

procedure tform1.cxgrid1dbtableview1customdrawindicatorcell(sender: tcxgridtableview; acanvas: tcxcanvas; aviewinfo: tcxcustomgridindicatoritemviewinfo; var adone: boolean);
var
  fvalue: string;
  fbounds: trect;
begin
  if (aviewinfo is tcxgridindicatorrowitemviewinfo) then
  begin
    fvalue := inttostr(tcxgridindicatorrowitemviewinfo(aviewinfo).gridrecord.index + 1);
    fbounds := aviewinfo.bounds;
    acanvas.fillrect(fbounds);
    acanvas.drawcomplexframe(fbounds, clbtnhighlight, clbtnshadow, [bbottom, bleft, bright], 1);
    inflaterect(fbounds, -1, -1);
    acanvas.font.color := clblack;
    acanvas.brush.style := bsclear;
    acanvas.drawtext(fvalue, fbounds, cxaligncenter or cxaligntop);
    adone := true;
  end;
end;
