AsyncFileUpload가 작동합니다. AsyncFileUpload 컨트롤을 반복 할 LinkButton을 누르면 파일 이름이 사라집니다. 파일 이름을 가져 와서 저장할 수있는 방법이 있습니까? FileName이 작동하지 않습니다. 코드 숨김 공유에별로 관심이 없지만이 문제를 해결하는 데 필요한 경우 그렇게 할 수 있습니다. 여기UpdatePanel의 Repeater에있는 AsyncFileUpload
protected void RptRequest_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "AddRequest")
{
FileUpload myFileUpload = (FileUpload)e.Item.FindControl("FileUpload");
if (myFileUpload.HasFile)
{
try
{
string filename = Path.GetFileName(myFileUpload.FileName);
myFileUpload.SaveAs(Server.MapPath("~/") + filename);
myStatusLabel.Text = "Upload Success";
}
catch (Exception ex)
{
myStatusLabel.Text = "Upload Fail" + ex.Message;
}
}
else
{
myStatusLabel.Text = "myFileUpload Has No File";
}
}
}

그리고 코드 숨김이 ItemCommand 이벤트를 시도 : 먼저하는 LinkButton와 클릭 이벤트를 제거하는 명령 이름을 추가
