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);
< <这一句报错> > 类型“GridView”的控件“GridView1”必须放在具 有 runat=server 的窗体标记内。
Response.Output.Write(ostringwriter.ToString());
Response.Flush();
Response.End();
}

添加下面这个重载方法即可
public override void VerifyRenderingInServerForm(Control control)
{
// Confirms that an HtmlForm control is rendered for

我给个现成的项目代码事例吧！！！！！！！！！！！
Private Sub Button_csv_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button_csv.Click
DataGrid1.Columns(1).Visible = True
DataGrid1.Columns(2).Visible = True
DataGrid1.Columns(3).Visible = True
DataGrid1.Columns(0).Visible = False
DataGrid1.Columns(13).Visible = False
Response.Clear()
Response.Buffer = True
Response.AppendHeader( "Content-Disposition ", "attachment;filename=Sheet1.xls ")
Response.ContentEncoding = System.Text.Encoding.GetEncoding( "utf-8 ") '
Response.ContentType = "application/ms-excel " '
Response.Charset = " "
Dim tw As New System.IO.StringWriter()
Dim hw As New System.Web.UI.HtmlTextWriter(tw)
DataGrid1.RenderControl(hw)
Response.Write(tw.ToString())
Response.End()
DataGrid1.Columns(1).Visible = False
DataGrid1.Columns(2).Visible = False
DataGrid1.Columns(3).Visible = False
DataGrid1.Columns(0).Visible = True
DataGrid1.Columns(10).Visible = True
End Sub
