How to call a function in ASP.NET automatically after a certain time has elapsed?

Let's say I have a Label on my page. In PageLoad() it's Text parameter is set to "This is my first text".

After, for example, 1 minute I want this Label to change it's text parameter to "This is my second text" (completely automatical开发者_StackOverflowly, without any interaction of a user with this site).

Any ideas are welcome. AJAX perhaps? How? Thank you!

You could use a timer like this:
