itextsharp를 사용하여 여러 pdf 문서 다운로드

Question

문서 목록과 환자 세부 정보가있는 다른 표가있는 트리보기가 있습니다. 내가 할 필요가있는 것은 treeview (select multiple ... checkbox enabled)에서 문서를 선택하고 그리드에서 환자를 선택하고 버튼을 클릭하면 ITEXTSHARP를 사용하여 모든 문서를 작성해야하는 경우입니다. 여러 문서가 작성되었습니다. 나는 버튼을 클릭

foreach(TreeNode node in TreeView1.Nodes) 
    { 
     if (node.ChildNodes.Count>0) 
     { 
      for(int i=0 ;i<(node.ChildNodes.Count);i++) 
      { 
       if (node.ChildNodes[i].Checked==true) 
       { 
        string nodevalue = node.ChildNodes[i].Value.ToString(); 

        if (nodevalue=="3") 
        { 
         foreach (GridViewRow row in GridView1.Rows) 
          { 
           if (row.RowType == DataControlRowType.DataRow) 
           { 
            CheckBox chk = row.FindControl("CheckBox1") as CheckBox; 
            if (chk.Checked) 
            { 
             Label lbl_name = row.FindControl("Label1") as Label; 
             Label lbl_dob = row.FindControl("Label3") as Label; 
             pdf_abcd(lbl_name.Text.Trim(), lbl_dob.Text.Trim()); 
            } 
           } 
          } 
        } 


        } 
       } 
      } 
     } 
    }

Answer 1

PDF 파일을 결합한 zip 파일을 만들어야한다고 생각합니다.

Answer 2

조금만 돌아가서 PDF를 무시하고 HTTP 요청과 응답에만 집중한다면 답을 얻어야합니다. 브라우저가 HTTP 요청 (버튼 클릭)을하면 서버는 응답을 하나만 보낼 수 있습니다. 당신은 코드가 여러 응답을 브라우저에 보내려하고 있습니다 (실패한 경우). 처음으로 Response.End이라는 파이프 라인이 호출되면 실제로 종료되고 나머지 코드는 실행되지 않습니다.

하나의 거대한 PDF를 한 번에 작성하고 개별 PDF를 만들고 모든 PDF가 포함 된 mergethem 또는 create a zip 파일을 만드는 것이 해결책입니다.

방법 1 :

Response.Clear(); 
Response.ContentType = "application/pdf"; 
Response.AppendHeader("Content-Disposition", "attachment; filename=foo.pdf"); 
Response.TransmitFile(filePath); 
Response.End(); 

방법 2 :

Process process = new Process(); 
process.StartInfo.UseShellExecute = true; 
process.StartInfo.FileName = outputPdfFile; 
process.Start();
