程序如下，现在的问题是不管奇行还是偶行，背景色都一样，我需要奇行是一中颜色，偶行是另一中颜色，拜托了，最好在偶的程序上修改偶比较看得懂，拜托拉，有多少分都拿去！
procedure TFrmEditTR_stQuota.DBGridEh1DrawColumnCell(Sender: TObject;
const Rect: TRect; DataCol: Integer; Column: TColumnEh;
State: TGridDrawState);
begin
if (FDmdTranMaster as TDmdTR_stQuota).QrySecond.RecNo mod 2 = 1 then
begin
DBGridEh1.Canvas.Brush.Color := $00FF0000;
end
else
begin
DBGridEh1.Canvas.Brush.Color := $00FFFFC2;
end;
DBGridEh1.DefaultDrawColumnCell(rect, datacol, column, state);
end;

icol1表示行
if odd(icol1) = true then
StringGrid1.FloatingFooter.Color := clWhite;//奇
else
StringGrid1.FloatingFooter.Color := clRed;//偶

是不是要先循环先判断一共有多少行？然后如果DEGRID的行是1，就一种颜色，2就另一种颜色
，如果按照这个思路，着段程序应该怎么写？

楼上的，怎么还是没用啊，背景色还是一样的，以下是我从往站上抄来，稍做了修改，你看看有什么问题？procedure TFrmEditTR_stQuota.DBGridEh1DrawColumnCell(Sender: TObject;
const Rect: TRect; DataCol: Integer; Column: TColumnEh;
State: TGridDrawState)
var
oldcolor:tcolor;
oldpm:tpenmode;
begin
if DBGridEH1.DataSource.DataSet.RecNo mod 2 = 1 then
DBGridEh1.Canvas.Font.Style := [fsBold];
DBGridEh1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
{上面是演示程序的原内容，以下是增加部分}
if DBGridEH1.DataSource.DataSet.RecNo mod 2 = 1 then
begin
oldpm:= MemberGrid.Canvas.pen.mode;
oldcolor:= MemberGrid.Canvas.Brush.color;
DBGridEh1.Canvas.Brush.color:=clyellow;
DBGridEh1.Canvas.pen.mode:=pmmask;
DBGridEh1.DefaultDrawColumnCell(Rect, DataCol, Column, State);
DBGridEh1.Canvas.Brush.color:=oldcolor;
DBGridEh1.Canvas.pen.mode:=oldpm;
end;

那个窗体继承，继承了Parent的了，所以就不用写了。

我先在是字体颜色不要变，只要背景颜色变呀，如果把DBGridEh1.Canvas.Brush.Color 该成DBGridEh1.Canvas.Font.Color ，只改变了字体的颜色，背景色并没有变

if (FDmdTranMaster as TDmdTR_stQuota).QrySecond.RecNo mod 2 = 1 then

->

if DBGridEH1.DataSource.DataSet.RecNo mod 2 = 1 then

我上边的程序是模版中的一段程序，已经用了很久，具体的如下：

private
{ Private declarations }
FArray : Array of String;
FRecord_Str: String;
FDBGird: TDBGridEH;
Procedure MoveRecord(vDataSet : TDataSet ; vOption :TDBOption );
Function IsSaveState(vDataSet : TDataSet):Boolean;
Function GetDataDec :TStrings;
Function GetDataValue(vCBX : TCustomComboBox) : TStrings;
Function GetFieldName(vCBX : TCustomComboBox) : String;
Procedure SaveEvent;
Procedure EditEvent;
Procedure AddEvent;
Procedure CancelEvent;
Procedure DeleteEvent;
Procedure QueryEvent(vDataSet : TADOQuery; vSQLStr ,vFieldName ,
vFieldValue , vCon : String ; vInt : Integer = 0);
procedure DBGridDrawColumnCell(Sender: TObject; const Rect: TRect;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DataCol: Integer; Column: TColumnEh; State: TGridDrawState);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

public
{ Public declarations }
TempDataSet , FADOQuery : TADOQuery;
FSQLStr : String;
FDBGrid : TDBGridEH;
~~~~~~~~~~~~~~~~~~~~~

procedure TTemplteFrm.DBGridDrawColumnCell(Sender: TObject;
const Rect: TRect; DataCol: Integer; Column: TColumnEh;
State: TGridDrawState);
begin
if gdSelected in State then
Exit;
if TDBGridEh(Sender).DataSource.DataSet.RecNo mod 2 = 1 then
(Sender as TDBGridEh).Canvas.Brush.Color:=clwhite
else
(Sender as TDBGridEh).Canvas.Brush.Color:=$00F2F2F2;
(Sender as TDBGridEh).DefaultDrawColumnCell(Rect,Datacol,Column,State);
end;

调用：
procedure TDataOutputFrm.Link;
begin
inherited;
FADOQuery := DataModuleFrm.PTCLXSCKSet;
SetDBGrid(PTCLCKDBGrid,DataModuleFrm.PTCLXSCKDS);
SetSQLStr('Select * From CommonOutput where CoState = ''WB'' and CoType = ''PT''');

PTCLCKDBGrid.ClassType Is TDBGridEH

if (FDmdTranMaster as TDmdTR_stQuota).QrySecond.RecNo mod 2 = 1 then
begin
DBGridEh1.Canvas.Brush.Color := $00FF0000;
問題就是上面用(FDmdTranMaster as TDmdTR_stQuota).QrySecond
而下面用的則是DBGriD驢唇對不上馬嘴

应该是DBGridEh1.Canvas.Font.Color

除非
if (FDmdTranMaster as TDmdTR_stQuota).QrySecond.RecNo mod 2 = 1 then
有问题

我先在知道为什么你们可以了，因为版本的问题，我是5。0版本的，所以运行不到这个效果

这个可以的，我试过才发上来的
