Welcome to the .NET MAUI for Beginners Series where you will learn the basics of building multi-platform apps with .NET MAUI for iOS, Android, macOS, and Windows from a shared C# code base. In this video, James shows off how to use the built-in navigation system of .NET MAUI to easily navigate between pages of the application with a URL based schema, and how to pass full objects as well.

I come back to this video everytime i need to add a new page lmao

Really useful for someone coming from MVVM in WPF, thank you! One question - is there any tool that will parse the project and create a navigation map for reference? Seems a tool like that would be useful for complex projects.

@Tajemniczy Рік тому

Big thanks for this:). I was thinking about starting something with xamarin but from what I see this MAUI will be better because also I will have desktop apps ^^:)

It’s simple: I see James quality footage - I like the vid and use the knowledge. Great explanations.

@risesandhineempowerment 10 місяців тому

Hey James - great lesson thanks and got it all working. What I can't work out how to do is to detect when the page is navigated away from using the back arrow at the top of the screen. I've tried every event I can find but none of them seem to fire. Not sure what I'm doing wrong. Thanks 😊

What if i the details page needs to pull the details from the server and show them in the view ? shall i call the server in the constructor of the view model or what ?

@faranahmadk7401 6 місяців тому

Hi James, I like all your videos But I have question. Is it possible to pass data to two different pages at the same time. How to do it ? I tried it but it goes to the first page then second page but I just want to pass the data without navigation. Please guide.

@lebeluet Рік тому

Question: Why didn't you create the Views folder to place the "DetailPage.xaml" file in this folder ?

@JamesMontemagno Рік тому

Just how I organize my code. Some folks like a folder named Pages or Views

@Remusqs1 9 місяців тому

The Go Back button is actually unnecessary in this case. It seems that the build-in navigation of Maui implements an "Auto Go Back" witch actually has a better and smoother transition

where i can read document at 11:46 (Transfer/Pass Variable type of Class.cs? And how to read/get/show it from Form Receive?

@GAMacky Рік тому

Great video. I just discovered an issue that I'm not sure how to resolve. The query parameter passed into the new page will not set to the query properties in the ViewModel until after the constructor of the viewmodel is completed. This means that I can't get any data to load inside constructor. For example, I pass an itemId from the collectionView page to the detail page, I'm not able to load the item object using the itemId until after the constructor is completed. So this means I can't use the community toolkit's [ObservableProperty] as I'll need to customize the set method on the query parameter property to load the item using the newly set itemId.

@MrJorgeandres12 11 місяців тому

I had the same issue, what I have done is load the data in the ApplyQueryAttributes() function, so you will load the data once the query parameters be set

Is there any way to pass collections between pages? Or raise some method from viewmodel when it's been navigated to?

Why not use the Item Tapped event method to navigate to DetailPage?

@Romahotmetytky Рік тому

And how are you going to UnitTest the Tap(string s) method huh ? you are using Static Shell class there for me that is a code smell, and now you cannot use user view model by different framework e.g wpf or winui cause you are depending on Shell

@strictnonconformist7369 10 місяців тому

This is a beginner's set of lessons. Myself, I'd pass in a reference via the constructor to an interface that does what is needed so it's not so tied to the framework details.

@sinsedrix 12 днів тому

Navigation seems so broken on windows. Mixing GoToAsync and PushAsync has hazardous behaviour. Back shell button works when it want. When navigation stack is over 2 element, app crashes. Ambiguous routes problem is recurrent. Would you consider making a new tuto about navigation with more use cases?

@SuchithM Рік тому

I'd suggest it be removed for the sake of Accessibility, as Microsoft in many aspects tries to provide for that. Myself, I have a degenerative inner ear disorder also slowly destroying my hearing, and difficulty processing speech anyway. I'm calling on James to have no background music for that reason.
