How to show progress bar at application level in Win RT application?
<p>I had two xaml pages like FirstPage.Xaml and SecondPage.Xaml .</p>

<p>On FirstPage.xaml I am generating pdf of all image recods by rendering image control available on my SecondPage.Xaml.
What I am doing is I navigate to SecondPage.Xaml from FirstPage and then in SecondPage's LoadState method I update the image control with image record from my database table then rendered that image in BitmapeImage and saved it in a file, after saving image to file I closed the SecondPage by Frame.GoBack() method then write this image file to pdf.</p>

<p>For adding all the records in table to pdf I used above logic and it is working properly.</p>

<p>I am just need to show Progressbar at Application level that "PDF is Preparing" which will be appear at top of the application page navigation.</p>

<p>I tried adding Progressbar to FirstPage.xaml get Closed when it navigates to SecondPage.xaml</p>

<p>Please help me, "How to show progress bar at top of application which not closed beyond page navigation?".</p>

<p>Thanks In Advance.</p>
