SharpKit.KnockoutJs Namespace

Knockout is a JavaScript library that helps you to create rich, responsive display and editor user interfaces with a clean underlying data model. Any time you have sections of UI that update dynamically (e.g., changing depending on the user’s actions or when an external data source changes), KO can help you implement it more simply and maintainably.

Hello world
class MyPage : Knockout
    static MyPage()
        // Here's my data model
        var viewModel = new MyViewModel
            firstName = observable("Planet"),
            lastName = observable("Earth")
        // Knockout tracks dependencies automatically. It knows that fullName depends on firstName and lastName, because these get called when evaluating fullName.
        viewModel.fullName = dependentObservable(() => viewModel.firstName.Value + " " + viewModel.lastName.Value);
        applyBindings(viewModel); // This makes Knockout get to work
class MyViewModel
    public Observable<string> firstName { get; set; }
    public Observable<string> lastName { get; set; }
    public DependentObservable<string> fullName { get; set; }
