Unlike other MVVM libraries we do not have a EventToCommand class. We use a short and more convenient way to bind events to commands.

Lets bind the Tapped event to a command in XAML:

<TextBlock Mvvm:EventBinding.Tapped="{Binding TappedCommand}" Text="Tap me"/>

Here is an example of a view model class with a command that handles an event from the UI:

public class SimpleViewModel
    public SimpleViewModel()
        TappedCommand = new EventCommand<Point>(OnTapped);

    public IEventCommand TappedCommand { get; private set; }

    private void OnTapped(Point point)
        // You can mark the event as handled by using the PreventBubbling property.
        // This property value will not be reset automatically.
        // So you can set it once in the constructor or update it anywhere.
        TappedCommand.PreventBubbling = point.X < 100;
