1、出了问题。代码如下
bd();//这是我绑定数据源的代码
Response.Clear();
Response.Buffer = true;
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());//两个参数"application/ms-excel", "User.xls"
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView2.RenderControl(hw);//出错的地方-----------------------------------------------
Response.Output .Write(tw.ToString());
Response.End();报错的内容是类型“GridView”的控件“GridView2”必须放在具有 runat=server 的窗体标记内。
说明：我的GridView2是放在runat=server 的form内的。
且里面没有模版列，只有数据列。
2、寻求导出Excel的源代码？好的坏的都行，酌情结贴。
3、在线等。

//override掉这个方法
public override void VerifyRenderingInServerForm(Control control)
{
//注释掉下面的代码，否则在asp.net2.0下会报错（注：GridView是asp.net 2.0下的控件，1.1下一些控件也可以导出成Excel或者Word）
//base.VerifyRenderingInServerForm(control);
}楼主是否缺少上述代码？
