No, you can not do this.

If you're expecting to port a winforms application to webforms feature for feature, you're going to be greatly disappointed. WebForms is still just a thin veneer over the http protocol; one that tends to peel up at the corner.

If you're trying to keep something on top via the web, you can't do that without a plugin, no matter what web platform you use.
