GridView导出到EXCEL出错，请求帮忙！

[tianhw1980]

在WEB界面上的GridView导出到EXCEL出错，请求帮忙！

导出的代码是在网上找的

protected void LinkButton1_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.Charset = "GB2312";
Response.AppendHeader("Content-Disposition", "attachment;filename=FileName.xls");
// 如果设置为 GetEncoding("GB2312");导出的文件将会出现乱码！！！
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.ContentType = "application/ms-excel";//设置输出文件类型为excel文件。
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

this.GridView1.RenderControl(oHtmlTextWriter);
Response.Output.Write(oStringWriter.ToString());
Response.Flush();
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{ }

但是报错，在
this.GridView1.RenderControl(oHtmlTextWriter);
说：
只能在执行Render()的过程中调用RegisterForEventValidation;

protected void 导出Excel(object sender, EventArgs e)
{


Export("application/ms-excel", "输出文件名.xls");

}
private void Export(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView列表.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}

好的，问题解决了，谢谢大家

现在我想的是通过一个按钮，将导出的数据的某一行传入到页面的一个TextBox上显示，

该怎么做呢？

比如，我只导出了一行数据，但是EXCEL会生成一个表头，数据在第二行，

我想要获取第二行的第二列

该怎么办？

直接在GridView上取不可以吗？
如果要在EXCEL中取的话，可以直接读取excel中的数据，不过这样比较麻烦

[tianhw1980]

我想的是实现一个导入导出

比如：A地的使用者导出了数据，只要送一个EXCEL文件到B地

那么B地就可以把数据导入数据库了

所以这是没办法的啊！

把EnableEventValidation属性设为False就可以了!
