ASP.NET에서 필터링 옵션을 어떻게 추가합니까?

Question

서버 정보를 표시하는 ASP.Net MVC 웹 페이지를 구축 중입니다. 또한 Management Studio를 사용하지 않고도 각 서버의 소유자를 편집 할 수 있습니다.

잘 작동하지만, 내가 선택한 ServerNames를 볼 수 있도록 필터링 기능을 추가하려고합니다 (머리글에 필터 기능을 구현 한 후에 Excel 스프레드 시트를 필터링하는 방법). 내가 서버에서 데이터베이스를 연결하고, 내가 표시하고있는 정보는 3 개 개의 다른 테이블에서입니다 :

일부 추가 정보 :

나는 다음 자습서를 사용하고있다.

도움을 주시면 대단히 감사하겠습니다.

은 이런 식으로 Index 컨트롤러를 변경합니다 : 이것은 내 컨트롤러 코드가

입니다 :

이 내 인덱스 뷰 코드

public ViewResult Index(string filter) 
{ 
    var serverlists = db.ServerLists.Include("Server_Group").Include("TeamMember"); 

    if (!string.IsNullorEmpty(filter)) 
     serverlists = serverlists.Where(sl => sl.Name.StartsWith(filter); 

    return View(serverlists.ToList()); 
} 

을 다음 변경하려면 목록 filtere가 필요할 때 {url}?filter=stringtosearchfor 필터를 사용하여 다시 게시 할보기 디. 이렇게하면 AJAX 스타일의 필터링은되지 않지만 의도 한 응답을 얻을 수 있습니다.
