I have a Listbox in an Ajax UpdatePanel, when the user clicks the submit button and navigates away from the page, I clear the data using ListBox.Items.Clear(); However, when the user clicks the back button in the browser the data is still in the ListBox.Items collection.. (Its invisible at first, but when you try and add a new item to the listbox, the old items show up again). *shrug* anyone ever had this problem?
