while(!tmprs->Eof){
       TGrpButtonItem* bt=new TGrpButtonItem(bt);
       bt->Caption=tmprs->FieldByName("组合名称")->AsString;
       ButtonGroup2->Items->AddItem(bt,k);
       k++;
       tmprs->Next();
     };
TGrpButtonItem* bt=new TGrpButtonItem(bt);
这个语句总是不行啊，请问下括号中究竟应该放什么东西才行啊？
晕，改成这样居然就行了：
TGrpButtonItem* bt=new TGrpButtonItem(ButtonGroup2->Items);
