안녕하세요 초보 빌더 입니다.

현재 테스트 할려고 소스코드를 짜봤는데 박히는 부분이 MouseUp 이벤트 함수에서 현재 선택한 체크박스가 몇번째 박스 인지 알고 싶습니다. 이벤트처리해야되는데 잘모르겠어요

혹시 추가적으로 체크박스를 선택 했을 때 stringgrid 2번째 열에 노란색, 체크박스 해제될때 회색으로 표시 할 수있는 방법이 없을까요?

* 별표시 부분 입니다.

void __fastcall TForm1::cbCheckMouseUp(TObject *Sender,
      TMouseButton Button, TShiftState Shift, int X, int Y)
{
        cbCheck1[cbCheck1->tag]->Checked = !cbCheck1[cbCheck1->tag]->Checked;                    <------------------ *
}

{
        for(int i=0; i<StringGridResult->RowCount; i++)
        {
                if(cbCheck1[i] != NULL)
                {
                        delete cbCheck1[i];
                        cbCheck1[i] = NULL;
                }
        }

        if(ComboBox1->ItemIndex == 0)
        {
                for(int i=0; i<3; i++)
                {
                        cbCheck1[i] = new TCheckBox(StringGridResult);
                        StringGridResult->Objects[0][i+1] = cbCheck1[i];
                        cbCheck1[i]->Parent = StringGridResult;
