I think the best approach is to use Session.

Hmmm let me see...
I think i have an idea. If i added an input button and used javascript history.back(); return false;
I can get back to the page before. But this will only work if u dont do a post back on page P2 right????
If i manage in my case to prevent going server side on page P2 then i will be able to get back to page P1 and maintain the data.
My problem is that i have an asp.net button on page P2 that loops through the grid and opens another page using also
javascirp window.open. If i manage to prevent this button from refreshing this page then i will be able to do it....
execuse me iam just thinking loud

That's Good. But why you are afraid to use session ? I think that is the think that you can implement easily.

Most people are instructed to avoid using the session, because it's the most expensive way to go.

my suggestion is u have to use session to fix it.no other go.
u cant keep data alive.

The best way to do this is to make p1 and p2 controls on the one page. Then, you can change which control is visible, and viewstate will maintain the state of your pages. The other way to do it, is to put the parameters that define the search on the querystring, so when your user goes back, the same search is repeated, because the querystring defines it.

what does 'difficult to select' mean ? It sounds like your firefox is not drawing the radio buttons well. You have to explain yourself better. If the buttons are too small, try using CSS to make them bigger perhaps ?
