如何从转发器导出的 excel 中删除前两列和超链接

Question

I am exporting data to excel from repeater control, which contains some hyperlinks in multiple columns and link buttons in first two columns. I want to remove all hyperlinks as well as remove or hide first two columns, when I export the data to excel from repeater control - "rptrExport". I am not getting any reference specially for repeater on internet. Below is my code:

Export button click even:

protected void btnExport_Click(object sender, EventArgs e)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.ClearContent();
        Response.ClearHeaders();
        Response.AddHeader("content-disposition", "attachment;filename=details.xls");
        Response.Charset = "";
        Response.ContentType = "application/vnd.ms-excel";
        StringWriter sw = new StringWriter();      
        HtmlTextWriter hw = new HtmlTextWriter(sw);      
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        rptrExport.RenderControl(hw);
        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();
    }

Code in aspx class for repeater:

 <asp:Repeater ID="rptrExport" runat="server" OnItemDataBound="rptrExport_ItemDataBound">
                                        <HeaderTemplate>

You have to convert it to string array then remove the wanted records.
