    Hi everyone. I am developing my first app and I am having a bit of a problem and not sure what it the general way to solve it..

    My app does a scrape of a website and returns a list of results to a pivotpage...

    I build a List<MyObject> where MyObject has all the data I am displaying then I bind it to the listbox using ListBox1.ItemsSource = MyList;

    This part is working just fine and I can link out from there to a details page for each item in the list...

    What I want is to be able to click the back button from the details page and have all of the listboxes still populated... Currently they are blank when I click the back button.

    Is there some setting like "isPostBack" on ASP.NET that needs to be turned on?
    Or do I need to store everything locally as well as display it and then repopulate it when the back button is clicked?
    Or is there a better tool to display/bind my data to that is better at remembering it's state?

    Thanks in advance...Sorry I don't have any code...I'm at work right now and it's on my home computer,,,

    Yes, that's a quite fundamental fact of WP7 programming: You have to save and restore any data that your page needs yourself.

    Just check the OnNavigatedTo and OnNavigatedFrom page methods in the source code of any non-trivial WP7 app to see the code there to save and restore state.
