图表+table

  protected void Button3_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);

            string imagePath = Server.MapPath(this.DaxonTechChartWeb1.ImagePath) + "//" + this.DaxonTechChartWeb1.ID + "." + this.DaxonTechChartWeb1.ImageType.ToString();
            oHtmlTextWriter.AddAttribute(HtmlTextWriterAttribute.Src, imagePath);


            tableExcel.RenderControl(oHtmlTextWriter);
            Response.Output.Write(oStringWriter.ToString());

            Response.Flush();
            Response.End();


        }

gridview：

    protected void Button_toExcel_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);
       //  turn off paging

        GridView1.AllowPaging = false;
        GridView1.Columns[0].Visible = false;
        GridView1.DataBind();
        GridView1.RenderControl(oHtmlTextWriter);
        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();
        // turn the paging on again
        GridView1.AllowPaging = true;
        GridView1.DataBind();

    }
