| Invalid postback or callback argument |
|
This is a common error that frequently plagues web developers and is often hard to work around. I've come across it several times and fixed it using a variety of solutions that are usually specific to even a particular page being worked on.
Today I watched in horror as this error popped up over and over, on users screens at a training that was being given for a web application that I helped develop. I couldn't understand why since I couldn't produce the error on the live version of the application, which was using the same set of code. When I got home I reviewed the web.config and discovered that I left Debug set to True. I changed it to False, and could no longer get the Invalid Postback error to occur. That's a tough lesson to learn. In addition to the constant error popping up, the performance was very poor as a result of running in debug mode.
It's important to mention that the error was being triggered when a user would click a Menu link and something on the page was still loading. |
