大家帮我看看下面的代码问题出在哪?
procedure TFrmCCCX.DBGrid1DrawColumnCell(Sender: TObject;
const Rect: TRect; DataCol: Integer; Column: TColumn;
State: TGridDrawState);
var
i: integer;
begin
if gdSelected in State then Exit;
//定义表头的字体和背景颜色：
for i :=0 to (Sender as TDBGrid).Columns.Count-1 do
begin
(Sender as TDBGrid).Columns.Title.Font.Name :='宋体'; //字体
(Sender as TDBGrid).Columns.Title.Alignment:= taCenter;
(Sender as TDBGrid).Columns.Alignment:=taCenter;
(Sender as TDBGrid).Font.Name :='宋体';
(Sender as TDBGrid).Font.Size :=11;
(Sender as TDBGrid).Columns.Title.Font.Size :=12; //字体大小
(Sender as TDBGrid).Columns.Title.Font.Color :=clblue;//字体颜色(红色)
(Sender as TDBGrid).Columns.Title.Color :=clinactivecaptiontext;//背景色(绿色)
end;
//隔行改变网格背景色：
if Query1.RecNo mod 2 = 0 then
(Sender as TDBGrid).Canvas.Brush.Color := clInfoBk //定义背景颜色
else
(Sender as TDBGrid).Canvas.Brush.Color := RGB(191, 255, 223); //定义背景颜色
//定义网格线的颜色：
DBGrid1.DefaultDrawColumnCell(Rect,DataCol,Column,State);//******************
with (Sender as TDBGrid).Canvas do //画 cell 的边框
begin
Pen.Color := $00ff0000; //定义画笔颜色(蓝色)
MoveTo(Rect.Left, Rect.Bottom); //画笔定位
LineTo(Rect.Right, Rect.Bottom); //画蓝色的横线
Pen.Color := clWindowtext;//$0000ff00; //定义画笔颜色(绿色)
MoveTo(Rect.Right, Rect.Top); //画笔定位
LineTo(Rect.Right, Rect.Bottom); //画绿色的竖线
end;
end;
按运行,出现错误:
Incompatible Types: 'DBGrids.TColumn' and 'Sailreport.TColumn'
注：我装的是D7，安装有Sailprint控件,如果注释上面带*号那行代码运行通过。

编译错
Incompatible Types--不兼容的类型

这个地方的Column 明明是Dbgrids.Tcolumn ~~编译器怎么认为是 Sailreport.Tcolumn阿~~
奇怪了~
你可以在开始判断一下 if sender is Tdbgrid then ~~~但也没道理啊！！
等找到原因了说一下~

你将dbgrid的引用单元放到Sailreport引用单元的前面试一下，
也许就ok了。。。

把它们引用的先后变一下,真的就可以了.给你加分.
