Automatic data filtering

hi all. I’m doing an app that have to le the user to show only the
data that belongs to a single year (the user can select this sort of
filtering interactively through a combo box ). I have to make this
filtering selection “persistent” betwenne my pages. Do i have to save
tha value of the year in my session? I think the qnaswer is “yes”…
how can i filter the data automatically, if it is possibile?


Storing it in the session would be the easiest way.
