急TStringGrid或者TDrawGrid嵌套上拉列表，知道的请进

急！TStringGrid或者TDrawGrid嵌套下拉列表，知道的请进！
使用C++Builder 2010 希望在TStringGrid 或者 TDrawGrid中通过使用TInplaceEditList(EditStyle=esPickList)
嵌套下拉列表！
整了好长时间没整出来了！望高手指点。

[解决办法]
//大致这样做，在Cell的相关事件里
 if( !m_ComboBox )
m_ComboBox = new TComboBox(this);

m_ComboBox->Visibel = false;
m_ComboBox->BorderStyle = bsNone;
m_ComboBox->Parent = StringGrid1;
m_ComboBox->Top =
m_ComboBox->Left = 
m_ComboBox->Width =
m_ComboBox->Height=
m_ComboBox->Visible=true;

楼主分明想要 TInplaceEditList 实现的.

用1楼方法也可以，简单，
其他就是沟通问题。

我来也！！！

首先添加一个单元(Unit)到工程中，命名为uDropListGrid，其中
uDropListGrid.h文件的内容如下：

C/C++ code

//---------------------------------------#ifndef uDropListGridH#define uDropListGridH#include <Windows.h>#include <Messages.hpp>#include <SysUtils.hpp>#include <Classes.hpp>#include <Controls.hpp>#include <Grids.hpp>typedef void __fastcall (__closure *TOnGetEditStyle)(int ACol, int ARow, TEditStyle &EditStyle);typedef void __fastcall (__closure *TOnGridEditButtonClick)(TObject *Sender, int ACol, int ARow);class TDropListGrid: public TStringGrid{private:    int FButtonWidth;    int FDropDownRows;    TOnGridEditButtonClick FOnEditButtonClick;    TOnGetPickListItems FOnGetPickListItems;    TOnGetEditStyle FOnGetEditStyle;    void __fastcall SetButtonWidth(int Value);    void __fastcall SetDropDownRows(int Value);    void __fastcall SetOnEditButtonClick(TOnGridEditButtonClick Value);    void __fastcall SetOnGetPickListItems(TOnGetPickListItems Value);    void __fastcall SetOnGetEditStyle(TOnGetEditStyle Value);    void __fastcall ButtonClick(TObject *Sender);    void __fastcall GetPickListItems(int ACol, int ARow, TStrings *Items);protected:     TInplaceEdit * __fastcall CreateEditor();     DYNAMIC TEditStyle __fastcall GetEditStyle(int ACol, int ARow);public:     __fastcall TDropListGrid(TComponent *AOwner);     __fastcall ~TDropListGrid();__published:    __property int ButtonWidth = { read=FButtonWidth, write=SetButtonWidth };    __property int DropDownRows = { read=FDropDownRows, write=SetDropDownRows };    __property TOnGridEditButtonClick OnEditButtonClick = { read=FOnEditButtonClick, write=SetOnEditButtonClick };    __property TOnGetPickListItems OnGetPickListItems = { read=FOnGetPickListItems, write=SetOnGetPickListItems };    __property TOnGetEditStyle OnGetEditStyle = { read=FOnGetEditStyle, write=SetOnGetEditStyle };};#endif
