Hi..
I have two pages in my web application. The user navigates to these pages through the help of tree navigation as well as tab navigation. The first page is called Campaign and the second page is called Schedule. The campaign page has several dropdowns as well as textboxes. Now I want to add a button in my campaign page, which will redirect the user to the schedule page. The user can create the schedules and then, when the user clicks the save button in the schedule page, i want to take the user back to the campaign page.
The problem is:
1. If the user is navigating to the schedule page through the tree navigation or the tab navigation, after making the entries in the schedule page, the schedule page should not be redirected to campaign page. But if the user is navigating to the schedule page through the Button click in campaign,the user should be redirected to campaign page.
2. In the campaign page, there are several fields. The user enters some values in the campaign page and then clicks the schedule button. After saving the data in the schedule page, when the page gets redirected to campaign, i want to retain the existing values that are entered in the campaign.

How to do this? Please help
