asp.net - Download of xls working in IE/Firefox but named as aspx page in Chrome -

-

i'm having issue chrome renaming export file default of page name export being initiated from. i've gone through related forum posts find , have tried suggestions - i'm not seeing recent posts within past couple of years.

my code export (before modification attempts) follows:

public static void exporttospreadsheet(object items, string name) {     httpresponse response = httpcontext.current.response;     response.clear();     response.clearheaders();     response.charset = "";     response.contenttype = "application/vnd.ms-excel";     response.addheader("context-disposition", "attachment;filename=\"" + name + "\"");      using (stringwriter sw = new stringwriter())     {         using (system.web.ui.htmltextwriter htw = new system.web.ui.htmltextwriter(sw))         {             system.web.ui.webcontrols.datagrid dg = new system.web.ui.webcontrols.datagrid();             dg.datasource = items;             dg.databind();             dg.rendercontrol(htw);             response.write(sw.tostring());             response.end();         }     } }

the above code works flawlessly in ie/firefox. resulting result headers received (per chrome net-internals) is:

cache-control: private content-type: application/vnd.ms-excel server: microsoft-iis/8.0 context-disposition: attachment;filename="dataexport.xls" x-aspnet-version: 4.0.30319 x-sourcefiles: =?utf-8?b?qzpctxlfrgf0yvxbvfnnxerldjqwxhbvcnrhbfxdr0lfqxv0b21hdglvbl9gcmftzxdvcmtcqxv0b21hdglvbl9ezwnrlmfzchg=?= x-powered-by: asp.net date: fri, 05 dec 2014 19:37:05 gmt content-length: 86493

i've tried several updates includes hard coding filename "test.xls", clearing content of response, setting buffer true, setting cachecontrol , pragma no-cache, , overriding verifyrenderinginserverform() in page's code-behind. response headers after applying these changes follows:

cache-control: no-cache pragma: no-cache content-type: application/vnd.ms-excel expires: -1 server: microsoft-iis/8.0 context-disposition: attachment; filename="test.xls" x-aspnet-version: 4.0.30319 x-sourcefiles: =?utf-8?b?qzpctxlfrgf0yvxbvfnnxerldjqwxhbvcnrhbfxdr0lfqxv0b21hdglvbl9gcmftzxdvcmtcqxv0b21hdglvbl9ezwnrlmfzchg=?= x-powered-by: asp.net date: fri, 05 dec 2014 19:10:23 gmt content-length: 86493

this still produces same results chrome not recognizing/accepting filename , defaults pagename downloaded filename.

any recommendations how fix issue appreciated.

i'm using chrome version 39.0.2171.71 m
