.net中将GridView中的部分内容或者全部内容导出到Excel中

Response.Clear();
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
Response.AddHeader("content-disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8) + ".xls");//此处为了处理保存名避免乱码
Response.Charset = "gb2312";
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GrantReleaseView.AllowPaging = false;//导出前先取消分页,以便能将所有数据导出。
GrantReleaseInfoBLL.Bind(campusId, depId, year, pageSize, pageIndex, out pageCount, GrantReleaseView);//再重新绑定一次数据
GrantReleaseView.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
GrantReleaseView.AllowPaging = true;//导出后先取消分页,以便能将所有数据导出。
GrantReleaseInfoBLL.Bind(campusId, depId, year, pageSize, pageIndex, out pageCount, GrantReleaseView);//再重新绑定一次数据
2.同时需要在代码中添加以下方法:重写一个空的VerifyRenderingInServerForm方法。
public override void VerifyRenderingInServerForm(Control control)
{
/*以确认在运行时为指定的ASP.NET 控件呈现HtmlForm 控件*/
}
3.在页面的page属性中加入EnableEventValidation = "false" .如:
<%@ Page Language="C#" AutoEventWireup="true" EnableEventValidation = "false" CodeFile="ExpertsList.aspx.cs" Inherits="ExpertsList" %>
4.要是需要是部分导出时:就将不需要的隐藏 方法如下:
GrantReleaseView.Columns[0].Visible = true;
GrantReleaseView.Columns[1].Visible = false;
GrantReleaseView.Columns[GrantReleaseView.Columns.Count-1].Visible = false;
GrantReleaseView.Columns[GrantReleaseView.Columns.Count-2].Visible = false;
将指定的列导出时隐藏
5.在导出的Excel中添加序列号
当需要在Excel表中包括序列号时:应该在Gridview中添加序列号这一列,在显示的时候隐藏,在导出时显示,就OK。
Gridview
竖着分:多个Column (列)
横着分:row , row (行)中又包含了多个cell 单元格.
