If you have ever written any App that involves some sort of messaging or real-time data, then you were likely confronted with the integration of data streams that originate from different sources. It can mean that you have to load cached data from disk, get data via an API call and/or instantiate a real time […]
In my 2 previous posts ReactiveUI Goodies–IReactiveDerivedList Filtering 1 and ReactiveUI Goodies–IReactiveDerivedList Filtering 2 I demonstrated how CreateDerivedList(), a method provided by ReactiveList can be used to implement filter scenarios. In this post I would like to explore how we can utilize CreateDerivedList() to archive dynamic grouping in a ListView. Grouping is often used to […]
In my previous post ReactiveUI Goodies–IReactiveDerivedList Filtering 1 I demonstrated how we can utilize CreateDerivedCollection() to filter a collection based on a single root list. I would like to further explore that example and demonstrate a more sophisticated filtering solution. But, before we can dive into the actual filtering code, we need to do some […]
In my last post Reactive Goodies–IReactiveDerivedList Basics I introduced IReactiveDerivedList and CreateDerivedCollection() respectively. Based on the outlined example I would like to show how to use a derived list to apply filtering easily. To demonstrate an interactive behavior, I have added a new ViewModel property and UI element to our little Todo Demo App. private bool _showTodoOnly; […]
Collections or lists are an important part of almost any App. Sequences of data need to be presented in a certain order to be able to be filtered and searched while the UI needs to reflect any changes to that data. Beyond simply listing data and informing the UI layer about Inserts and Deletes the […]
In my last post I talked about ReactiveList ReactiveUI Goodies – ReactiveList and I would like to dive a little bit more into collections. But before I do so, I would like to repeat a classical example of reactive programming – Search. Search or Filtering is a basic feature in many Apps and as simple […]
When programming Apps, or any software with a UI for that matter, we (the developers without designers) are challenged to make things look good. One important part of that challenge is icons. They are used for Buttons, in AppBars or as status indicators. In the world of high DPI devices with different scaling factors we […]
In the world of XAML, DataBinding and ViewModels – the ObservableCollection is the standard utility to light up any list of items. The ObservableCollection is part of the Framework Class Library (FCL) and implements the INotifyCollectionChanged interface. Basically the equivalent of INotifyPropertyChanged for collections. Any class implementing INotifyCollectionChanged needs to inform subscribers about items being […]
I have decided to start a new series of blog posts about practical programming. The goal of this series is to share some useful tools, coding practice and patterns I discover in my daily life of programming. Not only for you but for my future self. Who does not find answers in his own blog […]
