winforms-reactiveui-demo

Winforms .net Core 6 + ReactiveUI and DynamicData

Goals

The goal of this demo is to show how to deal with the most common scenarios for a Desktop application. The application implements:

• Dependency injection with Splat, views, and services.
• How to use a main entry-point with Routing and UserControls.
• How to open a new Form (outside the main routing).
• Routing between screens/views.
• Binding data and execute commands between View and ViewModel.
• Bind to reactive properties (as calculated fields).
• How to bind data to a ListBox via DataSource. More info on DataSource.
• How to deal with UI events (via ReactiveMarbles.ObservableEvents.SourceGenerator). See the note below.
• How to use Interactions to show Modal form with or without DialogResult.
• How to subsribe to UI changes like TextBox and ComboBox with sort info, and refresh the data in the UI.
• How to use Dynamic Data and deal with Collections. See the note below.
• etc.

Note related to RxUi WinForms events

RxUI WinForms doesn't support Bind yet. So there is a temporary solution to support events that don't implement INotifyPropertyChanged.

Note related to Dynamin Data

The demo is using Dynamic Data, but be carefull that WinWorms supports only binding to BindingList<T>. More info on BindingList.

Routing and Views structure

  graph TD;
      A[Shell :: IScreen * Form]-->|Route|B[ItemsView :: ItemsViewModel * UC];
      A-->|Route|C[ItemsDDView :: ItemsDDViewModel * UC];
      B-->|Interaction|D[AskConfirmation * MessageBox];
      D-->|Yes > Modal Form|E[ItemTagsView :: ItemTagsViewModel * Form];
