RT，在线等高手解决问题，希望贴出完整代码，本人是新手，分数不是问题，感谢！

将其字段的checkbox设为true就会有checkbox 了

Ehlib是第三方控件,不过做数据库编程来说已经替代默认BCB自带的DBGrid什么的控件了,属于增强版.老妖网站上有

不要第3方控件应该怎么实现呢

up

…不是吧

C/C++ code

void __fastcall TForm1::OnDrawColumnCell1(TObject *Sender,
      const TRect &Rect, int DataCol, TColumn *Column,
      TGridDrawState State)
{
        int Select_Check[2]={DFCS_BUTTONCHECK,DFCS_BUTTONCHECK |DFCS_CHECKED} ;

    if (Column->Field->DataType== ftBoolean )
    {
        TRect RecTemp;
        RecTemp.left = Rect.Left;
        RecTemp.right = Rect.Right;
        RecTemp.top = Rect.Top;
        RecTemp.bottom = Rect.Bottom;

        DBGrid1->Canvas->FillRect(Rect);
        DrawFrameControl(DBGrid1->Canvas->Handle,&RecTemp,DFC_BUTTON,
            Select_Check[Column->Field->AsBoolean?1:0]);
    }
}
//—————————————————————————

void __fastcall TForm1::CellClick(TColumn *Column)
{
         if (!Column->Field->DataSet->Eof)
    {
        if (Column->Field->DataType == ftBoolean )
        {
            SaveBoolean();
        }
    }

}
//—————————————————————————

void __fastcall TForm1::KeyDown(TObject *Sender, WORD &Key,
      TShiftState Shift)
{
     if ((Key ==VK_DOWN) && (ADOQuery1->RecNo==ADOQuery1->RecordCount))
        Key=NULL;

    if ((Key==VK_SPACE)&& (DBGrid1->SelectedField->DataType==ftBoolean))
    {
        SaveBoolean();
    }
}
//—————————————————————————
    void __fastcall  TfrmGatByRec::SaveBoolean()//这段出错，不知道格式怎么写
{
    DBGrid1->SelectedField->DataSet->Edit();
    DBGrid1->SelectedField->AsBoolean=!DBGrid1->SelectedField->AsBoolean;
    DBGrid1->SelectedField->DataSet->Post();
}

幫我看下上面代碼是實現什么功能，注釋那是出錯了，謝謝

沒人幫忙？？？？？？？？？
