Windows Phone后退按钮

Question

I need to go back to a particular page when I click on a button. more like custom back button.

I can go exact page, if I know what is the page is,

private void button_click(object sender, RoutedEventArgs e)
{
    Frame.Navigate(typeof(Page1));
}

Also I can go back to the previous page by

if(this.Frame.CanGoBack)
{
    Frame.GoBack();
}

But how can I jump to the page before the previous page at once?

Any record of page history?

Answer 1

You can use NavigationServices.BackStack to access on an history of your previous pages.

But you have not specific method to go back from 2 pages at once. However, if you would jump to the page before the previous page you have just to called NavigationServices.GoBack() two times.

Moreover, if you would go back to a specific page, you can know its index between backstack and make a loop with the GoBack method.

Answer 2

You can get all pages from BackStack as a List :

var lstAllStackPages = this.Frame.BackStack.ToList();

and make a for loop to get your specific page and navigate to it.

Answer 3

Thank you @CoderDennis, I figured it out. hope it will help to someone else. I wanted to move back to the Main page if I have come along the Main page,

foreach (PageStackEntry stack in Frame.BackStack)
{
 //check if stack contains history of the main page. (Solution name: Helloworld)
 if (stack.SourcePageType == typeof(HelloWorld.MainPage))
   {
    Frame.Navigate(stack.SourcePageType);
    break;
   }
}
