When creating a binding in Xamarin.Forms, the default is that you create an OneWay binding (except for input elements that have TwoWay bindings), this means that it updates the view from the ViewModel whenever the value in the ViewModel changes. But often you don't need an OneWay binding, you only need an OneTime binding, but […]

Introduction Lists are a fundamental and inescapable part of mobile applications. Think of your favourite email client or social media app; without a doubt they present scrolling vertical list of emails or posts. In Xamarin.Forms, we can use the ListView to display vertical scrolling lists of items. However, Xamarin.Forms 4.3 introduced CollectionView as its successor. CollectionView simplifies many aspects of ListView and also adds new features.

Introduction In part two of our Migrating ListView to CollectionView series, we'll cover how to migrate your ListView cells so you can use them in a CollectionView. Cells Setting your cell with a ListView uses a DataTemplate but requires your view to be contained within a ViewCell class. It looked a bit like this: Data Templates <ListView.ItemTemplate> <DataTemplate> <ViewCell> <controls:ItemView/> </ViewCell> </DataTemplate> </ListView.

Introduction In part three of our Migrating ListView to CollectionView series, we will look at handling user interaction in CollectionView's by adding cell tap, swipe context actions, and pull to refresh. Tapping Cells Tapping cells on ListView we used the ItemTapped event which I will omit for brevity because I assume everyone already knows how to use it. Because CollectionView has more features than ListView, it's a little different to get item tap setup.

In Praise of Elevated Values Always Wear Protection You know what you don't get when you work with Enumerables and Observables? This. I hate NullReferenceExceptions. There's a very simple reason why you don't get them, of course, and that's because both IEnumerable and IObservable are a sort of a collection, and a collection is special in LINQ and Functional Programming terms because of how you apply functions to it.
