좋은 기사. 감사. 나는 이것 (위)에 질문을 가진다. 우리의 응용 프로그램에서 우리는 사용자가 유가 증권의 목록을 다운로드 할 수 있도록 하려면, 그들의 가격 날짜와 가격 (빈 다운로드) 엑셀에서 나는 위의 그리드 보기 방법을 사용 할 수 있어요. 하지만 그때 사용자가 각 행의 가격을 입력 하 고 다시 서버로 우리가 어디에 삽입 DB를 업로드 같아요. 문제는 우리가 몇 가지 가격을 입력 하 고 파일을 업로드 하려고 하면, 그것은 잘못 된 파일 형식을 말하는 휴식. 우리는 업로드 된 엑셀 파일을 읽을 수 제트 oledb 4.0를 사용 하 고 있습니다. 내가 손으로 excel을 만들고 보안, 가격 날짜와 가격을 입력 한다면 업로드와 데이터베이스 삽입 코드는 작용 한다. 당신이 배치한 부호에서, 그것은 문제점 일 수 있는 무슨이 명확 하 게 얻고 있지 않다. 그러나, 나는 당신이 당신이 겨냥 하 고 있는 유사한 부호 대 본에 좋은 본보기를 대표 하는이 자습서를 따르는 것을 건의 한다: c # 및 VB.Net를 사용 하 여 서식 ASP.Net에서 Excel로 내보내기 GridView이 공유 주셔서 감사 합니다, 정말 나를 위해 유용 하다 , 또한이 링크를 한 번 봐가지고<a href=`zeeshanumardotnet.blogspot.com/…/creating-reports-in-excel-2007-using.html& Reports in Excel 2007 using EPPlus (Header, Footer, Comments, Image, Formatting, Shape and Formula) Alternatively, you can use the OpenXML libraries, and export to an Excel 2007 file. protected void btnExportToExcel_Click(object sender, EventArgs e) CreateExcelFile.CreateExcelDocument(listOfEmployees, “Employees.xlsx”, Response); You get this message because you are opening a file in Microsoft Office Excel 2007 that contains content that does not match the files extension.

Its because AJAX & Response.write don’t go together.

By calling Response.Write() directly you are bypassing the normal rendering mechanism of ASP.NET controls. The bits you write are going straight out to the client without further processing (well, mostly…). This means that UpdatePanel can’t encode the data in its special format. In this tip, we have seen how to export data to an Excel file in ASP.NET. It is rather easy, but many new developers struggle with it so I wrote this to help them. The first is the main namespace in the EPPlus library and the second is required to make the MemoryStream class available. The final one is the namespace for the Product class in this particular project. The GetProducts method returns a List from a LINQ query. The code in the button click event handler calls this method and binds the data to the GridView. The GridView will not be displayed or rendered to HTML, however. The main reason for binding the data is because the GridView provides a fairly simple way to get the column names for the spreadsheet via the HeaderRow property.
