在头部<head>加入
打印事件
<script language=javascript> function doPrint() 
{ 
bdhtml=window.document.body.innerHTML; sprnstr= "<!--startprint-->"; eprnstr= "<!--endprint-->"; prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17); prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr)); window.document.body.innerHTML=prnhtml; window.print(); 
} </script> 在<body>间加入
打印按钮和打印设置<OBJECT id="WebBrowser" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" height="0" width="0" VIEWASTEXT> </OBJECT> <div align="center"> <a href="javascript:; " onClick= "doPrint() "><img src="images/d-y.jpg" border="0" /></a> <input class="NOPRINT" onclick="document.all.WebBrowser.ExecWB(8,1)" type="button" title="打印设置"> </div>打印的内容
打印的内容<!--startprint--> <form id="form1" runat="server"> <table class="tabp" width="650" height="700" align="center"> <tr> <td align="center" valign="top" bgcolor="#FFFFFF"> <!--打印的内容--> </td> </tr> </table> </form><!--endprint--> 页面设置按钮是为了去除页脚页面，默认是会打印页面的路径，即http://www.???.aspx?Id=?和页面的Title。
那俩个标记一定要放在form外面，要不会多一行内容出来。
gridview导出到excel
导出事件protected void btnLoad_Click(object sender, EventArgs e) { Response.Buffer = true; Response.Charset = "gb2312"; Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); Response.AppendHeader("content-disposition", "attachment;filename=\"" + System.Web.HttpUtility.UrlEncode(DateTime.Now.ToString("yyyy-MM-dd"), System.Text.Encoding.UTF8) + ".xls\""); Response.ContentType = "application/ms-excel"; this.EnableViewState = false; StringWriter tw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(tw); GridView1.RenderControl(hw); Response.Write(tw.ToString()); Response.End(); }需要增加一下方法，要不会报错
需增加的一个方法public override void VerifyRenderingInServerForm( Control control ) {}
