導出所有數據到Excel使用GridView與分頁啓用..在asp.net與c＃

Question

我想導出數據到Excel。我有GridView與分頁啓用。當我使用HtmlTextWriter下載數據時，它只下載到GridView中的可見記錄。我們可以下載單個Excel文件中的所有記錄嗎？並且下載的數據應該和GridView中的排序狀態一樣？

客戶端源代碼

<asp:GridView ID="gvDetailFleet" runat="server" DataSourceID="SqlDataSource2" 
     AllowPaging="false" AllowSorting="True" AutoGenerateColumns="true" 
     DataKeyNames="OracleId" CellPadding="4" ForeColor="#333333" 
     GridLines="None" > 
     <RowStyle BackColor="#EFF3FB" /> 
     <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" /> 
     <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" /> 
     <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" /> 
     <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" /> 
     <EditRowStyle BackColor="#2461BF" /> 
     <AlternatingRowStyle BackColor="White" /> 
</asp:GridView>

     StringWriter sw = new StringWriter(); 
     HtmlTextWriter htw = new HtmlTextWriter(sw); 
     gvDetailFleet.AllowPaging = false; 
     gvDetailFleet.HeaderRow.Style.Add("background-color", ""); 
     for (int i = 0; i < gvDetailFleet.HeaderRow.Cells.Count; i++) 
     { 
      gvDetailFleet.HeaderRow.Cells[i].Style.Add("background-color", ""); 
     } 
     gvDetailFleet.RenderControl(htw); 
     Response.Write(sw.ToString()); 
     Response.Flush(); 
     Response.End(); 
    } 

    public override void VerifyRenderingInServerForm(Control control) 
    { 

    }

Answer 1

你可以嘗試做這樣的

GridView gv = new GridView(); 
     gv.DataSource = sourceList; //Your datasource from database 
       gv.DataBind(); 
       Response.ClearContent(); 
       Response.Buffer = true; 
       Response.AddHeader("content-disposition", "attachment; filename=Preferred_Funds-" + DateTime.Now.ToShortDateString() + ".xls"); 
       Response.ContentType = "application/ms-excel"; 
       Response.Charset = ""; 
       StringWriter sw = new StringWriter(); 
       HtmlTextWriter htw = new HtmlTextWriter(sw); 
       gv.RenderControl(htw); 
       Response.Output.Write(sw.ToString()); 
       Response.Flush(); 
       Response.End(); 

Answer 2

//試試裏面的這段代碼按鈕

Response.Clear(); 
    Response.AddHeader("content-disposition", "attachment;filename=ExportData1.xls"); 
    Response.Charset = ""; 
    Response.ContentType = "application/vnd.xls"; 
    StringWriter StringWriter = new System.IO.StringWriter(); 
    HtmlTextWriter HtmlTextWriter = new HtmlTextWriter(StringWriter); 

    //batigol 
    GridView1.AllowPaging = false; 
    GridView1.DataSource = Session["uu"]; 
    GridView1.DataBind(); 
    // 

    GridView1.RenderControl(HtmlTextWriter); 
    Response.Write(StringWriter.ToString()); 
    Response.End();
