GridView匯出資料到Excel

1、在aspx頁面page標記中設定enableeventvalidation屬性

<%@ page language="c#"enableeventvalidation = "false"autoeventwireup="true" codefile="operationloglist.aspx.cs"

inherits="usermanage_operationloglist" %>

2、匯出資料到excel

response.clear();

response.buffer = true;

response.charset = "gb2312";

// 如果設定為 getencoding("gb2312");匯出的檔案將會出現亂碼！！！

response.contentencoding = system.text.encoding.utf8;

system.io.stringwriter ostringwriter = new system.io.stringwriter();

system.web.ui.htmltextwriter ohtmltextwriter = new system.web.ui.htmltextwriter(ostringwriter);

// 設定gridview控制項不可以分頁，繫結資料，匯出資料到excel

this.gvloglist.allowpaging = false;

execquery();

this.gvloglist.rendercontrol(ohtmltextwriter);

response.output.write(ostringwriter.tostring());

response.flush();

response.end();

// 設定gridview控制項可以分頁，重新繫結資料

this.gvloglist.allowpaging = true;

execquery();

3、重寫方法verifyrenderinginserverform()，必須有，方法體為空就可以。

public override void verifyrenderinginserverform(control control)
