Xamarin.Forms Shell Quick Tip - Easy Back Navigation

Xamarin.Forms Shell introduced route based navigation to Xamarin.Forms applications to easily navigate through applications and also pass data through query properties. Sometimes in your application it is not always about navigating forward to pages, but it is about navigating backwards when your users perform an action. Another reason you may have to navigate backwards through the app is when you are using modal pages and there is no physical back button such as on an iPhone. So, let’s see how easy it is to enable this functionality in your app.

Xamarin.Forms Shell Back Navigation

With the launch of Xamarin.Forms 4.6 came a brand new way to navigate backwards and can be combined with query properties. To navigate backwards you can use the same navigation patterns you are used to in terminal or the command line with ... That is right, just use .. and a page will be popped from the stack.

Xamarin.Forms Shell Quick Tip - Modal Navigation

In the Shell quick tip series we explored navigation features of Shell including passing data and going back easily. Today, I want to talk about a common feature of navigation where a new page pops up over the current page. This is different than traditional navigation where a page is pushed onto the stack. A modal page requires the user to perform an action to close the page such as tapping a close button or completing registration. With Xamarin.Forms Shell we can easily navigate using modal pages with a specific property

Presentation mode

Xamarin.Forms Shell handles all navigation styles through a property called PresentationMode. You can use it to perform modal navigation with or without animations. Additionally, you can use it with non-modal navigation to control how pages are pushed onto the stack. The mode I prefer to use is ModalAnimated to get that nice slide up from the bottom effect.

Shell.PresentationMode="ModalAnimated"

This property goes directly into the Content page top element of your page:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="App11.Views.ModalPage"
             Shell.PresentationMode="ModalAnimated">

You are also able to set it directly in the code behind if you are using C## markup for your user interface.

Shell.SetPresentationMode(this, PresentationMode.ModalAnimated);
