Till yesterday my ASP.NET website working amazingly in IE
8/9 browser without any issue. Today morning one of my client complained that
website is not working in IE 10.
Immediately I opened my website in IE 10 and try to click
one of link button.
Boom Boom…JavaScript error “__doPostBack is undefined”
I had gone through few Microsoft articles and found that .NET
2.0, 3.0, 3.5 and 4.0 frameworks are unable to detect IE 10 browser.
There are ton of solutions are written but none of these
worked directly for me.
We can resolve this issue either Machine level or
Application/Website level
Solution:
1. Remove “_browserCapabilitiesCompiler.compiled” file from Website Bin folder if exists. If this file exists none of other solutions will work. Because every time you request the page asp.net engine return the browser compatibility data from above file only.
2. For Application level, download IE 10/11 browser xml file ( IE10.browser ) from Microsoft website and copy into website App_Browser folder.
3. For Machine level,
i) download IE 10/11 browser xml file ( IE10.browser ) from Microsoft website
ii) copy to C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\Browsers
iii) Run C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regbrowsers –i
iv) Run iisreset
Now everything should work as you expected.
Happy Coding :)
