Recently we run a website with user feedback under IE 11 <asp:LinkButton> Click "__doPostBack" is not defined ", after some Google, finally know the reason: ASP. NET may not be able to identify some of the latest version of the browser, They are also often viewed as low-level browsers. (That is, JavaScript is not supported.) ）
See: Http://blogs.msdn.com/b/scott_hanselman/archive/2011/10/28/asp-net-ie10-dopostback-javascript-ff5.aspx
I follow the solution provided by this article has not been resolved, so as prompted to try to repair with a single site.
Create a new browser file (. browser) under Project root app_browsers to match the useragent of IE11, so that the. NET Framework recognizes that this is a known browser that can normally output scripts to the client.
Enter the following in the file and save it.
