webforms - Generating and downloading an `Excel` document breaks `ASP.net` LoginStatus -

-

in asp.net web application have page shows (not complicated) table. have implemented button when (registered) members clicks on it, browser downloads table excel document

the code generate excel follow:

        dim response httpresponse = httpcontext.current.response         ' first let's clean response.object         response.clear()         response.charset = ""         dim filename string = mappath("~/ex1.xls")         ' set response mime type excel         response.contenttype = "application/vnd.ms-excel"         response.addheader("content-disposition", "attachment;filename=""" & filename & """")         ' create string writer         using sw new stringwriter()             using htw new htmltextwriter(sw)                 ' instantiate datagrid                 dim dg new datagrid()                 dg.datasource = dt                 dg.databind()                  dg.rendercontrol(htw)                 response.write(sw.tostring())                 response.[end]()             end using         end using

the problem code breaking somehow aspn.net loginstatus when try log out after downloading excel (the "log out" buttom visible @ application) every click on buttom download same excelover , on (once per click). if reload window or change page "log out" work again.

this "log out" link when inspecting chrome:

<a id="ctl00_ctl00_maincontent_loginstatus1" href="javascript:__dopostback('ctl00$ctl00$maincontent$loginstatus1$ctl00','')">log out</a>

i have tried make excel download other page using:

onclick="window.document.forms[0].target='_blank';"

and opens new tab, download excel, close tab (fast process) still keeps breaking logout link.

and run out of ideas, help, code, hint or whatever possible solution fix problem welcome.

open new page within blank target, , let new page generate excel
