You can stop back navigation by set e.Cancel in back key press event.

In MainPage.xaml.cs constructor:

OnBackKeyPress += (s, e) =>
{
    if (MessageBox.Show("", "", MessageBoxButtons.OkCancel) == MessageBoxButtons.Cancel)
    {
        e.Cancel = true;
    };
};

Please handle the BackKeyPress button in the Application page to handle the back key press.

In Page.xaml file in the element add this code 

BackKeyPress="PhoneApplicationPage_BackKeyPress"

it should look like 

<phone:PhoneApplicationPage BackKeyPress="PhoneApplicationPage_BackKeyPress"
..//other attributes .. >

in event handler you write the code as follows 

private void PhoneApplicationPage_BackKeyPress(object sender, System.ComponentModel.CancelEventArgs e)
        {
             MessageBoxResult mb =  MessageBox.Show("You want exit the page", "Alert", MessageBoxButton.OKCancel);

            if( mb != MessageBoxResult.OK)
            {
                e.Cancel = true;
            }

        }

It's possible to catch when the user exits pressing the Back button, but it is not possible to stop the application from being made "dormant" when the user presses the hardware Start button or Search buttons.
