Javascript - Redirecting The Whole Page From Script Inside Iframe?

Im looking for a way to redirect to another page, when i click a link in the iframe. i dont want just the iframe to redirect, but the whole window.

is this possible?

preferably in javascript or in asp.net if possible

EDIT: When i try the answers i get redirected to the source of the iframe, not to the source of the site the iframe lies on... Ill show you the code

function redirect() {
window.top.location.href = "./Nyheter.html";
}

As i dont want the code to be static, so that i can use it on many pages without changing the url, i want to do it this way, alt. get the url from db... but preferrably this way, Solution? Also, forgot to mention. The pages are not on the same domain, they are on different ones..
