ok. I have a search controller called ct_Ricerca that permits to search an article, then the information of this article that I search, they are submit to modify controller that it permits tu modify this article and the input box are compile with information that they are received by ct_Ricerca controller for the user can modify this article. But my problem is that if the user has mistaken, he can click over Ricerca Avanzata link and the page is redirect to ct_Ricerca for a new research, but finaly I would have that this new research is precompiled with previous data of article.

Excuse me for my bad englesh and I hope that you have understood the same one. I have also linked 2 image for views of controllers ct_Ricerca and Modify.
