I've been using my own Error reporting module which was combination of simple c# and jQueryUI Dialog. Problem is that once error or success occurs i do write it's value to session. It does work pretty good on pages with Responce.Redirect on error but not on pages where i catch an error and then return to same form.

My question is why does session which added pre-postback fails to load in pages where i have return statement on some condition.

And if there another way to save errors and success message except in session ? Maybe global variables or something like that ...
