I have a stable application where one function suddenly stopped working, after upgrading from .NET 4 to .NET 4.5. The error has been isolated to an event not firing and it has been confirmed beyond any doubt (on 2 servers and 3 workstations), that this error only happens after the .NET 4.5 upgrade (and did not happen before).
从.NET 4升级到.NET 4.5之后，我有一个稳定的应用程序，其中一个函数突然停止工作。错误已被隔离到未触发的事件，并且已经确认（在2台服务器和3个工作站上），此错误仅在.NET 4.5升级之后发生（之前没有发生）。
I have the following:
我有以下内容：
- An empty aspx that only contains a usercontrol (don't ask)
- 一个只包含usercontrol的空aspx（不要问）
- The user control contains a GridView that is loaded with content after a postback.
- 用户控件包含一个在回发后加载内容的GridView。
- The GridView contains a LinkButton.
- The Text comes from an Eval
- 文本来自Eval
- It also has an OnDataBinding event that sets the CommandArgument
- 它还有一个设置CommandArgument的OnDataBinding事件
- GridView包含一个LinkButton。 Text来自Eval它还有一个设置CommandArgument的OnDataBinding事件
- The GridView contains an OnRowCommand.
- GridView包含一个OnRowCommand。
The event in the OnRowCommand is fired in .NET 4.0 and is not fired in .NET 4.5.
OnRowCommand中的事件在.NET 4.0中触发，并且不会在.NET 4.5中触发。
Any clues?
有什么线索吗？

UPDATE
I simplified my code and got closer to the core of the problem. I found that it was caused by AllowCustomPaging="True" on the GridView. After removing this, the postback works fine.
我简化了我的代码并更接近问题的核心。我发现它是由GridView上的AllowCustomPaging =“True”引起的。删除后，回发工作正常。
