I am working on a windows phone application.

I noticed that after I select particular item in listbox on Page-A and navigate to page-B, on page-B if I press "back" key, the item on page-A in listbox is remain selected.

But I want the page-A Items Refresh or Reload when go to page-A on "back" key press. 

I tried to implement the BackKeyPressed event handler of the page but it does not seem worked for me.

Anyone has any good idea with this? thank you
