Hello johnkainn,

I don't think that link applies to you (and it is not best practice either as discussed in the thread).

The simple answer is unfortunately no. Partly because of the reasons indicated in the thread mentioned above. You cannot instantiate the partial class (aspx.cs) without loading the whole page. If you have a function that needs to be used both from a page and from another class then it is better for you to move that function out of the page and into a common class where it can be called from wherever is appropriate.

Regards,

TimCottee's way would also work and i would use this method also.  you can sort of build your own library's by having your own classes.  

However, your question could it be done?  A resounding yes as shown by the link.  Should it be done?  Nothing wrong with it...just better to place methods in a class if you're going to use them constantly.  One of the major pluses of OOP is reusability.

silemone,

The link you gave doesn't actually imply anything of the sort, all this talks about is whether it is possible to place code-behind files in the app_code folder (which it demonstrates is possible though not recommended). It doesn't in any way refer to any method for calling a function coded within that code-behind file from a class that is not part of the page that loads it.
