Default Xamarin forms navigation page animation is not working when using master details page
I am setting the master page from App.Xaml.cs
MainPage = new NavigationPage(new MasterDetailPOS() { });
When I am navigating a page from another page,the second parameter is for animate.
Navigation.PushAsync(new Page1(),true)
page navigation animation not working.
When I am not using master detail page then this animation working fine.
so how to solve this?

I am creating an application in Xamarin Forms (4.0) for Android (Android 8.1).
My main page is a MasterDetailPage where I set the detail page to:
this.Detail = new NavigationPage(new SomePage());
When I want to navigate the detail to another page (so that the 'back' button works correctly) I just do:
this.Detail.Navigation.PushAsync(new NavigationPage(new SomeOtherPage());
This all works fine but I am left with an additionl navigation bar with the back button:
If I do NavigationPage.SetHasBackButton(this, false); the back button goes away but the navigation bar is left so I have a big blue rectangle on top of my page. If I do NavigationPage.SetHasNavigationBar(this, false); then both the navigation bar and the titlebar (with hamburger menu) dissappear! Is there a way to just hide the navigation bar with the back button but leave the master/detail title bar (with hamburger menu)?
It seems that the way I've tried to make it work is not really supported by Xamarin Forms. If you navigate the Detail away to another page you effectively loose access to the Master part of the MasterDetailPage (at least on some devices). My attempt to avoid this by wrapping the target Detail page into another NavigationPage works in the Emulator but that is simply by accident.
you only need one instance of NavigationPage
this.Detail.Navigation.PushAsync(new SomeOtherPage());
You can assign the new MasterDetailPage to the root and then handle back pressed. As this isn't suppose to work you must hack a bit.
Make sure that your MainPage is set only to MasterDetailPage.
Once, I had a case that somebody did something like this:
MainPage = new NavigationPage(new MasterDetailPage());
Of course, it should be defined like:
MainPage = new MasterDetailPage();
Then, your DetailPage should be defined only once as it follows:
Detail = new NavigationPage(new MyPage());
I'm using Xamarin Forms 3.6.
I want to hide the back button in the UWP app.
In the UWP App.xaml.cs OnLaunced I've added.
SystemNavigationManager
.GetForCurrentView()
.AppViewBackButtonVisibility = AppViewBackButtonVisibility.Collapsed;
I've also added it to each ContentPage (using dependency injection) so that in the constructor of each page runs the above code.
Each content page, I've also added:
NavigationPage.SetHasNavigationBar(this, false);
I always still seem to get the back button in the title bar on UWP.
Any ideas in Xamarin Forms UWP how to hide and keep hidden the back button?
For your requirement, please invoke SetHasBackButton static method in the page where you want to hide back button like the following.
public ItemDetailPage(ItemDetailViewModel viewModel)
{
InitializeComponent();
NavigationPage.SetHasBackButton(this, false);
BindingContext = this.viewModel = viewModel;
}
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());
