근본 원인 : 자동화 피어 API에 대한 재귀 호출이 유효하지 않습니다.

Question

우리는 약 2 년 동안 WPF Tookit DataGrid 및 .NET 3.5를 사용했습니다. 그리고 예외를 throw하는 두 가지 경우가 있습니다. "자동화 피어 API에 대한 재귀 호출이 유효하지 않습니다." 이상하고 eratic 한 종료, 아주 몇몇 PC에는 그런 문제점이있다.

케이스 하나 :가

드롭 다운 combox (드롭 콘텐츠 대조군으로서 WPF Tookit 데이터 그리드)가 해결 될 수

: 그리고

protected override AutomationPeer OnCreateAutomationPeer() 
{ 
    return null; 
} 

이 용액 WPF Recursive call to Automation Peer API is not valid 내지 .

케이스 2 :

WPF Tookit 데이터 격자 셀 템플릿은 드롭 combox (드롭 콘텐츠 대조군으로서 WPF Tookit 데이터 격자)를 가진 Temlate 열을 갖는다. 위의 해결 방법으로 해결할 수 없습니다.

많은 스레드 다만 어떤 사람이 자동화 피어 API에 대한 재귀 호출의 근본 원인에 대한 생각을 알고 있나요,이 문제에 대한 프린터 본체의 솔루션을 유효하지 않습니다?

Answer 1

나는 이것이 오래된 스레드라는 것을 알았지 만 프로젝트를 다시로드 한 후 똑같은 문제가 생겼다.

중요한 변경 사항은 RoboForm을 시험 버전으로 설치했고 만료되었다는 것입니다.

매우 쉽고 일관성있게 다시 만들 수 있습니다. 제거한 후에 문제가 사라졌습니다.
