. 하지만 아무것도 유형 입력 영역에 다음 도시를 보여줍니다. 나는 지역에 대한 별도의 기능을 작성했지만 무엇이 잘못 됐는지 모르겠습니까? 만약 가능하다면 도시 트리보기 및 영역 treevie에 대한 다른 조건과 동일한 기능을 사용하십시오 w.Code는 반복되지 않으므로 매우 좋습니다.사용하는 여러 트 리뷰 위젯
도시를 선택한 다음 값을 도시 TextBox에 입력하고 영역을 선택한 다음 도시 TextBox에서 값을 설정합니다. 별도의 TextBox에 값을 넣는 방법 City TreeView 값을 도시 TextBox 및 Area TreeView 값에 영역 TextBox에 넣습니다.
