ASP. IE11 dopostback is null or undefined null or undefined

Personally think that this problem is generally not in accordance with the norms of writing, but lazy people have lazy ways.

Page refactoring generally solves this problem, but there is still a workaround for situations where rewriting is inconvenient.

Workaround:

1. Copy the file Ie11.browser to C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\Browsers, The path may vary depending on the operating system and the. NETFramework version.
2. Start Cmd.exe as an administrator and switch to directory C:\Windows\Microsoft.NET\Framework\v4.0.30319.
3. Enter the command "Aspnet_regbrowsers-i" after the carriage return, the command does not include the quotation marks section.
4. Enter the command "IISRESET" after the carriage return, the command does not include the quotation marks section.
5. Wait for the command to finish, IE should be able to do it.

Ie11.browser is a text file with the following contents:
