Is it possible to export gridview without checkbox and linkbutton as normal

protected void Button1_Click(object sender, EventArgs e)
    {
        PrepareGridViewForExport(GridView1);
        string attachment = "attachment; filename=KALYANMANTAP_BOOKED_LIST_BY_WEBMASTER.xls"; 

        Response.ClearContent();

        Response.AddHeader("content-disposition", attachment);

        Response.ContentType = "application/ms-excel";

        StringWriter stw = new StringWriter();

        HtmlTextWriter htextw = new HtmlTextWriter(stw);        
        GridView1.AllowPaging = false;
        bind();        
        GridView1.RenderControl(htextw);
        Response.Write(stw.ToString());
        Response.End();
    }

    private void PrepareGridViewForExport(Control gv)
    {

        LinkButton lb = new LinkButton();

        Literal l = new Literal();

        string name = String.Empty;

        for (int i = 0; i < gv.Controls.Count; i++)
        {

            if (gv.Controls[i].GetType() == typeof(LinkButton))
            {

                l.Text = (gv.Controls[i] as LinkButton).Text;

                gv.Controls.Remove(gv.Controls[i]);

                gv.Controls.AddAt(i, l);

            }

            else if (gv.Controls[i].GetType() == typeof(DropDownList))
            {

                l.Text = (gv.Controls[i] as DropDownList).SelectedItem.Text;

                gv.Controls.Remove(gv.Controls[i]);

                gv.Controls.AddAt(i, l);

            }

            else if (gv.Controls[i].GetType() == typeof(CheckBox))
            {

                l.Text = (gv.Controls[i] as CheckBox).Checked ? "True" : "False";

                gv.Controls.Remove(gv.Controls[i]);

                gv.Controls.AddAt(i, l);

            }

            if (gv.Controls[i].HasControls())
            {

                PrepareGridViewForExport(gv.Controls[i]);

            }

        }

    }
