인사말, CascadingDropDown의 선택한 값 적절성을 사용하는 데 문제가 있습니다.C# ASP.NET AJAX CascadingDropDown 선택한 값 속성 문제
나는 그 (것)들 각각을 위해 ajax CascadingDropDown를 가진 3 ASP 드롭 다운 컨트롤을 가지고있다.
데이터를 3 CascadingDropDown에 바인딩해도 문제가 없지만 제 문제는 CascadingDropDown을 다시 바인딩하는 것입니다.
내가 원하는 것은 GridView에서 선택된 값을 가진 CascadingDropDown을 전달하기 위해 선택된 값을 가진 레코드를 선택하는 것입니다.
아래 코드를 게시하고 있습니다.
1ASP.NET 코드.
2 코드는 그리드보기에서 선택한 레코드를 처리합니다.
3 데이터를 3 CascadingDropDown에 바인딩하는 웹 서비스.
선택한 값으로 캐스케이드 드롭 다운에 데이터를 리바 인딩하는 방법을 알려주십시오.
내 코드에 표시된 것과 같이 선택된 값을 사용했지만 작동하지 않으며 오류가 없습니다.
