Registering RoutedEventHandler in UWP template control

Question

I'm having difficulty finding how to register a RoutedEventHandler in UWP. I'm attempting to code a template control that has event properties similar to ContentDialog's:

PrimaryButtonClick="ClickEvent"

Where ClickEvent is defined in the cs file. I'm only just getting the hang of templates, but I believe I want to do something that looks like this:

<Button Content="{TemplateBinding PrimaryButtonText}" Click="{TemplateBinding PrimaryButtonClick}"/>

Currently, all I can find is references to WPF versions of this type of code:

 public static readonly RoutedEvent ValueChangedEvent =
        EventManager.RegisterRoutedEvent("ValueChanged",
RoutingStrategy.Direct, typeof(RoutedPropertyChangedEventHandler<double>),
typeof(NumericBox));

    public event RoutedPropertyChangedEventHandler<double> ValueChanged
    {
        add { AddHandler(ValueChangedEvent, value); }
        remove { RemoveHandler(ValueChangedEvent, value); }
    }

    private void OnValueChanged(double oldValue, double newValue)
    {
        RoutedPropertyChangedEventArgs<double> args =
    new RoutedPropertyChangedEventArgs<double>(oldValue, newValue);
        args.RoutedEvent = NumericBox.ValueChangedEvent;
        RaiseEvent(args);
    }

But of course the types have changed. Can someone point me in the right direction?

Unfortunately, the concept of RoutedEvent (bubbling, tunneling) is not available in UWP currently. You can just create a classic event however instead:

public event EventHandler PrimaryButtonClick;

protected void InnerButton_Click(object sender, EventArgs e)
{
    PrimaryButtonClick?.Invoke( sender, e );              
}

Bubbling of events is possible for some predefined events, but it is not yet possible to allow bubbling for custom events in current version of UWP.
