Disable navigating back on back button mouse click

[Steve887]

I want to disable back navigation in my app. I have hidden the back button, however if I click the back button on my mouse the app still navigates to the previous page.

This seems to come from the OnMouseDown event in NavigationView:

protected override void OnMouseDown(MouseButtonEventArgs e)
{
	if (e.ChangedButton == MouseButton.XButton1)
	{
		GoBack();
		e.Handled = true;
	}
	base.OnMouseDown(e);
}

There doesn't seem to be any way to override this. I have tried hooking into the OnBackRequested event and setting Handled to true, but this does nothing. I know you can cancel navigation in the Navigating event, but there's no way to know if this came from a normal navigation, or from navigating back.

Is there any way to do this?

It seems that one way to cancel this currently is like this, which isn't great:

private void RootNavigation_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    if (e.ChangedButton is MouseButton.XButton1 or MouseButton.XButton2)
    {
        e.Handled = true;
    }
}
