Chrome is exporting aspx file instead of xls

I use the code attached to export data in xls. It works fine in any browser, except Chrome, where the file is exported as aspx instead xls. It is something wrong with my code or it's a browser setting that shoud be modified? Thanks

Response.Clear();
                    Response.AddHeader("content-disposition", "oferta");
                    Response.ContentType = "application/vnd.ms-excel";
                    Response.Charset = "";
                    StringWriter stringWrite = new System.IO.StringWriter();
                    HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); 
if (gv.Rows.Count>0)
                    {
                        htmlWrite.Write("<b>Client selectat:</b>");
                        gv.RenderControl(htmlWrite);
                        htmlWrite.WriteBreak();
                    }
string html = stringWrite.ToString();
                    string pattern=@"(\p{Sc})?";
                    System.Text.RegularExpressions.Regex rgx=new System.Text.RegularExpressions.Regex(pattern);
                    html = rgx.Replace(html, "");
Response.Write(html);
HttpContext.Current.Response.End();

Haven't tested the code, but http://my.opera.com/lamhoanghiep/blog/2010/08/05/export-gridview-to-excel might work for you. Looks like they're adding

HttpContext.Current.Response.ContentEncoding = Encoding.Unicode
HttpContext.Current.Response.BinaryWrite(Encoding.Unicode.GetPreamble())

try
Response.AddHeader("Content-Disposition", "attachment; filename=oferta.xls");

not working either way (Encoding or adding .xls)

the problem appears when I'm trying to export more than 1 gridview. At 1 gridview export, the output is in xls format

MMeijer

maybe you're calling Reponse.End() twice?

nope
i have attached a sample for at least 2 gridviews

Response.Clear();
                    Response.AddHeader("content-disposition", "oferta.xls");
                    Response.ContentType = "application/vnd.ms-excel";
                    Response.Charset = "";

StringWriter stringWrite = new System.IO.StringWriter();
                    HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); 
GridView gv = (GridView)Master.FindControl("SelectionGridView");
                    if (gv.Rows.Count>0)
                    {
                        htmlWrite.Write("<b>Client selectat:</b>");
                        gv.RenderControl(htmlWrite);
                        htmlWrite.WriteBreak();
                    }
                    FormViewCustomerDataMV.RenderControl(htmlWrite);
                    htmlWrite.WriteBreak();
                    if (GridViewStandardOffersVF.Rows.Count > 0)
                    {
                        htmlWrite.Write("<b>Oferta standard voce mobila:</b>");
                        GridViewStandardOffersVF.RenderControl(htmlWrite);
                        htmlWrite.WriteBreak();
                    }
                    if (GridViewStandardOffersVFSMS4All.Rows.Count > 0)
                    {
                        htmlWrite.Write("<b>Oferta standard SMS4All:</b>");
                        GridViewStandardOffersVFSMS4All.RenderControl(htmlWrite);
                        htmlWrite.WriteBreak();
                    }
                    if (GridViewStandardOffersCompet.Rows.Count > 0)
                    {
                        htmlWrite.Write("<b>Oferta competitie:</b>");
                        GridViewStandardOffersCompet.RenderControl(htmlWrite);
                        htmlWrite.WriteBreak();
                    }
                    if (GridViewCustomOffers.Rows.Count > 0)
                    {
                        htmlWrite.Write("<b>Oferta customizata voce mobila:</b>");
                        GridViewCustomOffers.RenderControl(htmlWrite);
                        htmlWrite.WriteBreak();
                    }
                    string html = stringWrite.ToString();
                    string pattern=@"(\p{Sc})?";
                    System.Text.RegularExpressions.Regex rgx=new System.Text.RegularExpressions.Regex(pattern);
                    html = rgx.Replace(html, "");
                    //StringReader reader = new StringReader(html);
                    //Write xls document
                    Response.Write(html);                    
                    //end current Response
                    HttpContext.Current.Response.End();
