Excel로 목록보기 내보내기 (문제 해결)

Question

웹 응용 프로그램에서 작업 중이므로 Excel로 목록보기를 내보낼 수 있어야합니다. 목록 뷰가 바인딩되어 있지만 데이터 내보내기 기능이 작동하지 않습니다. 이 기능은 <asp:LinkButton> 및 <asp:Imagebutton>에 걸려있는 것으로 보입니다. 이 문제를 해결하는 방법을 알고있는 사람이 있습니까?

public void ExportIntoExcel(ListView lvExport, string Header, string FileName) 
{ 
    try 
    { 
     System.Web.HttpContext.Current.Response.Clear(); 
     System.Web.HttpContext.Current.Response.ContentType = "application/vnd.ms-excel"; 
     System.Web.HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=" + FileName + ".xls"); 
     System.Web.HttpContext.Current.Response.Charset = ""; 
     System.Web.HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache); 
     StringWriter stringWrite = new StringWriter(); 
     stringWrite.Write(Header); 
     stringWrite.WriteLine(); 
     HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); 
     HtmlForm frm = new HtmlForm(); 
     lvExport.Parent.Controls.Add(frm); 
     frm.Controls.Add(lvExport); 
     frm.RenderControl(htmlWrite); 
     System.Web.HttpContext.Current.Response.Write(stringWrite.ToString()); 
    } 
    catch (Exception ex) 
    { 
    } 
    finally 
    { 
     System.Web.HttpContext.Current.Response.End(); 
    } 
} 

protected void export_Click(object sender, EventArgs e) 
{ 
    if (paidlv.Visible == true) 
    { 
     ExportIntoExcel(paidlv, "Income Summary", "incomesummary"); 
    } 
} 

업데이트 : 여기에 전체의 목록보기가 그래서 당신은 <asp:LinkButton>s 및 <asp:Imagebutton>s을 참조 할 수있다 .

당신은 내가 제목을 편집 한

private void DataTableToExcel(DataTable dataTable) 
{ 
    StringWriter writer = new StringWriter(); 
    HtmlTextWriter htmlWriter = new HtmlTextWriter(writer); 
    GridView gridView = new GridView(); 
    gridView.DataSource = dataTable; 
    gridView.AutoGenerateColumns = true; 
    gridView.DataBind(); 
    gridView.RenderControl(htmlWriter); 
    htmlWriter.Close(); 

    Response.Clear(); 
    Response.AddHeader("content-disposition", "attachment;filename=FileName.xls"); 
    Response.Charset = ""; 
    Response.Write(writer.ToString()); 
    Response.End();
