1、如果出现下面的错误提示可用重载VerifyRenderingInServerForm方法解决。
错误提示:
类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内
在后台文件中重载VerifyRenderingInServerForm方法,如:
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}
2、如果设置为 GetEncoding("GB2312"),导出的文件将会出现乱码。
可用Response.ContentEncoding = System.Text.Encoding.UTF7;
或者Encoding.UTF8等来解决，不过导入格式和字体上个人感觉UTF7比UTF8效果好些；
因人而异了：）
相关代码如下：
Web.config配置：
ASPX页面代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
http://www.w3.org/1999/xhtml" >
无标题页
