问题
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).
I have the following:
- An empty aspx that only contains a usercontrol (don't ask)
- The user control contains a GridView that is loaded with content after a postback.
- The GridView contains a LinkButton.
- The Text comes from an Eval
- It also has an OnDataBinding event that sets the CommandArgument
- The GridView contains an OnRowCommand.
The event in the OnRowCommand is fired in .NET 4.0 and is not fired in .NET 4.5.
Any clues?
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.
