You'll just see a "UserControl" placeholder there in the IDE unless you run
the page.

And in you case you won't see the usercontrol even if you run it because
both the <html> and <body> tag is missing in the aspx file.

Note that you can't place the start tag in one file and place the end tag in
another. In that case the browser and/or web server won't be able to tell
where your usercontrol should be placed.
