json을 통해 jQgrid에 500 개가 넘는 레코드를 바인딩 할 수 없습니다.

Question

JSON을 통해 jqGrid에 500 개 이상의 레코드를 바인딩 할 수 없습니다. 요구 사항은 jqGrid의 150000 레코드를 바인딩하고 페이지 매김을 추가하는 것입니다.

SELECT 쿼리에 TOP 400을 추가하면 레코드를 볼 수 있지만 TOP 500은 공백으로 표시됩니다.

1) 우리는 우리의 maxJsonLength 초과인지 여부를 확인해야합니다 : 다음은 내 코드입니다.

무엇을 : Web.config를 이동하고 다음 코드

<system.web.extensions> 
    <scripting> 
     <webServices> 
      <!-- Try increasing this value to a larger value (Int.MaxValue used below) --> 
      <jsonSerialization maxJsonLength="2147483644"></jsonSerialization> 
     </webServices> 
    </scripting> 
</system.web.extensions>
