WPF에 대한 이전 컨트롤을 수정했습니다. 경보 목록을 표시하는 DataGrid를 만들어야합니다. DataGrid의 첫 번째 열은 플래그 아이콘과 날짜를 보유하는 DataGridtemplate 열입니다. 사용자가 버튼을 누르면 알람이 인식되고 깃발 아이콘이 사라집니다. MVVM 패턴을 사용하고 있습니다.DataGridTemplateColumn 업데이트
문제점은 datagridtemplate 열의 플래그를 업데이트 할 수 없다는 것입니다. 확인 상태를 0에서 1로 변경하면 (알람이 울린 후) 플래그가 사라지지 않습니다. 컨트롤을 다시로드하고 서버에서 알람을 다시 가져 오면 서버의 상태가 실제로 업데이트되었음을 나타내는 플래그가 다시 표시되지 않습니다. 그래서 어떻게 든 내 코드는 작동하지만 UI가 업데이트되지 않습니다. 나는 또한 같은 방식으로 알람의 설명을 변경하려고 시도했는데 그 열은 업데이트되었습니다.
