I'm using prism and had a MasterDetailPage with some pages that is accessible from that. But, in some of this pages, I can navigate to other pages that is not accessible from the MasterPageDetail Menu, but menu is still accessible with sliding action. I'll post some prints to try explain.
That's is a page that is accessible from MasterPageDetailMenu
When the user is accessing this page, he can access the MasterPageDetail Menu. But if the user select an item of the list or click in "Plus" Floating Button, the app navigate to other Page where MasterPageDetail Menu shouldn't be accessible.
But, as you can see on the next image, if the user slide the page from the left to right, the MasterPageDetail Menu is still accessible
How can I avoid this behaviour?
In the App class, my code for navigate to MasterPageDetail is:
await NavigationService.NavigateAsync("Menu/Navigation/TipoItensCardapio")
In this case, menu is my MasterPagelDetail.
The code for navigate from TipoItensCardapio page to the second page is:
NavigationService.NavigateAsync("TipoItemCardapioEdit");
If you intend for a specific page to not allow the drawer to be swiped out it sounds like you should probably be pushing it as a Modal instead of a normal Page. For example:
await Navigation.PushModalAsync(new YourPage());

I'm using MasterDetail page in my Xamarin.Forms app for UWP.
When i click on menu icon and then navigate to other page from that menu, an extra header appear on that page. But while menu is open, that header goes away like below.
When navigate from menu, page looks like this:
But while menu open, header disappearing:
Hope for better solution
I am using Prism for Xamarin Forms application development.
May be because I am new to both Prism and Xamarin Froms because of which I am facing a basic issue with the navigation.
Let me start with the details of my implementation and then the issue at hand.
I have a MasterDetail Page (named Home) which is my main page.
There are a few menu items in the Master Page. One of them is Partner.
On Click of Partner menu item, NavigationService.NavigateAsync("Navigation/Partner") method is called. Where "NavigationService" is of type "INavigationService".
This opens a page called "Partner" which is a tabbed page (TabbedPage). The first tab is a contentpage called "PartnerAll".
PartnerAll page contains a listview. On click of a list view item, a new page is opened "PartnerDetails" by calling NavigationService.NavigateAsync("Navigation/PartnerDetails", parameters, false, true);
On PartnerDetails page, I have added a toolbaritem called "Cancel".
Issue: When "PartnerDetails" page opens up, "Cancel" item shows up twice, as shown in the screenshot:
screenshot of partner details page with two cancel buttons
Where is it I am going wrong. What should I do to make it work?
Please assist.

You’re pushing two NavigationPage’s onto the Navigation Stack. This would result in two Navigation bars. You can see in your screenshot you have both a back and a hamburger menu icon.
You should just pass in the identifier string for your destination page, instead of pushing another instance of the NavigationPage onto the stack
do it like so NavigationService.NavigateAsync(PartnerDetails);
I am using Xamarin Forms with Prism. How do you navigate from the MasterDetail.Master to a ContentPage that is not part of the MasterDetail (that is, I don't want to just update the detail and continue to be part of the Master/Detail relationship)? The use case is like the Gmail app when you click on Settings from the Hamburger menu. It takes you out of the Master/Detail and you are now in a NavigationPage/ContentPage with a back button to get back to the MasterDetail page.
If you were not using Prism you could go to the Detail page and do a Navigation.PushAsync from there:
var mdp = Application.Current.MainPage as MasterDetailPage;
mdp.IsPresented = false;
await mdp.Detail.Navigation.PushAsync(new ContentPage2());
But I don't see how to do this using Prism navigation.

Assuming your Application.Current.MainPage is a MasterDetailPage. Current Detail in the MasterDetailPage is NavigationPage(new ContentPage1()).
In your ContentPage1, you have 2 options to navigate to ContentPage2:
Option 1: Show ContentPage2 in current navigation stack
You will be pushing ContentPage2 into the same Navigation stack of ContentPage1. Back button in navigation bar will be added automatically.
// Call this code in ContentPage1
_navigationService.PushAsync("ContentPage2");
Option 2: Show ContentPage2 modally
You are presenting the page modally and in a completely new navigation stack. You will need to add Back button in the NavigationBar and handle the click event with your own code.
// Call this code in ContentPage1
_navigationService.PushAsync("NavigationPage/ContentPage2", null, true);
When show screen, navigation is showing at the Top.But Back button is not showing.
When i use Navigation.PushAsync method then back button is showing.
I am using below code.
Navigation.PushModalAsync(new LoginSelection());
how can i show backbutton at left side of Modal screen.
When you call PushModalAsync(), you are creating an another Navigation Stack of Modals.Thus, your LoginSelection() page is not added to the Page Navigation Stack,but it is added on Modal Navigation Stack.
Thus,there are no pages in your modal stack and that's why back button is not appearing

Xamarin Forms Reverse PushModalAsync
I have several navigation pages that go several levels deep. Each time the user navigates to another page, an additional Back button is added to the top.
Navigation.PushAsync(new NavigationPage(new SettingsPage()));
Do I have to manually turn off the navigation bar prior to Pushing the new page or is there some type of setting for this?
Thanks.
Like Sushi mentioned in the comment, you're already in navigation page, you do not have to push a new NavigationPage every time.
Just use:
Navigation.PushAsync(new SettingsPage());
