Routed events in uwp

I'm having difficulty finding how to register a RoutedEventHandler in UWP. I need to have an event handler in parent class which can control access to all child classes inside it.

Currently UWP cannot customize routing events like WPF. In UWP, you can consider using EventHandler instead of RoutedEventHandler:

public class ParentModel
{
    public event EventHandler TestEvent;

    public void DoSomething()
    {
        //do other things...

        TestEvent?.Invoke(this, EventArgs.Empty);
    }
}

Usage

var parent = new ParentModel();
parent.TestEvent += HandleTest;

...

private void HandleTest(object sender, EventArgs e)
{
    var parent = sender as ParentModel;
    // do something...
}

Thanks.
