Building an MVP Framework for .NET. Part 4: Strongly Typed Associations

, 25 Apr 2008 Ms-PL
In this article we continue developing a Model-View-Presenter framework for .NET platform. The new features we are implementing here are strongly typed asscoiations between controllers, views and tasks for higher convenience and type safety.

    /// windows forms presentation mechanism. Inherit your view classes
    /// from this one and override IView members if necessary.

    /// <remarks>
    /// This class also implements <see cref="INotifiedView"/> interface,
    /// which tells the views manager to notify the view on such events
    /// as view initialization and activation. Default implementation
    /// methods do nothing but descendant classes may override them to
    /// add some functionality.

    /// - <see cref="WinFormView{T}"/> - with a strongly typed association
    /// to the controller and, thus, higher type safety.</para>
    /// </remarks>
    /// <example>
    /// In this example we declare a view type by deriving it from the
    /// WinFormView class without a need to manually implement IView
    /// interface.

    /// [WinformsView(typeof(MyTask), MyTask.MyView)]
    /// partial class MyView : WinFormView
    /// {
    ///     public MyView()
    ///     {

    ///         (Controller as MyController).MyAction();
