RadGrid가 EntityDataSource에 바인딩 된 경우 자동 삭제 오류

Question

EntityDataSource에 바인딩 된 RadGrid가 있습니다. 일부 열은 바인딩 된 엔터티의 탐색 속성에 바인딩됩니다. 레코드를 삭제하려고하면 다음 오류가 발생합니다.

오류 : Sys.WebForms.PageRequestManagerServerErrorException : 'Vehicle.VehicleNo'라는 속성이 삽입, 업데이트 또는 삭제 작업 중에 엔티티에서 발견되지 않았습니다. 바인딩 표현식으로 지정된 특성이 데이터 소스에서 사용 가능한지 확인하십시오.

탐색 속성 대신 일반 외래 키 ID를 사용하도록 선택하면 모든 항목이 작동합니다. 수동으로 처리하면 삭제를 쉽게 얻을 수 있습니다. 그러나 나는 "그냥 자동이. 너무 일을 어떤 아이디어에 삭제할 수있는 방법이있을거야 생각 해요?
