I cannot really imagine well usage of PagePlugInAttribute Class.
What is some example of real usage for this?
If i remember correctly it was used for hooking on datafactory events etc. It was used if you wanted to separate the code, like in a module and didn't want to use Global.asax.
Ah, ok. I can imagine this but can you post some “working” example?
Found an old blogpost by Allan regarding this with an example:http://allantech.blogspot.in/2007/10/how-to-extend-general-page.html
