HR 시스템의 회사 휴일을 추적하는 페이지가 있습니다. 그러나 지금은 종료 날짜를 편집하려고 시도하는 경우 휴일과 사용자가 우연히 시작 날짜 이전의 종료 날짜를 실수로 입력하면 여전히 모두 유효성이 검증되고 편집이 데이터베이스 테이블에 기록됩니다.asp.net 편집 템플릿 유효성 검사 컨트롤 그룹이 실행되고 false를 반환 할 때 C# IsVaild가 False로 바뀌지 않음
내가 누락 된 부분은 페이지를 항상 True로 확인하는 것입니다. 또한 유효성 검사 컨트롤 집합을 사용하는이 페이지에서 DetailsView를 사용하고 있으며 유효하며 무언가가 유효성 검사를 통과하지 못하면 false로 유효성을 검사합니다.
protected void HolidaysDS_Updated(object sender, SqlDataSourceStatusEventArgs e)
{
if (e.Exception != null)
{
lblNullUpdate.Text = "One of your updated fields is invalid. Your update did not occur.";
lblNullUpdate.Visible = true;
e.ExceptionHandled = true;
}
}
protected void gvHolidays_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
Page.Validate("EditValidationControls");
if (Page.IsValid == false)
{
e.Cancel = true;
}
lblNullUpdate.Visible = false;
}
사용자가 업데이트에 null을 전달하고 경우에 예외를 처리 내 현재의 C#은 그 또한 페이지의 유효성을 검사하고 모든 유효하거나 아니었다면 확인해야 할 이벤트입니다.
