Command Based Postback?

I need to be able to from C# launch a postback.

I have a command button that launches a function, I also have a javascript
function that then keeps you from firing any other objects on the page, but
when the function finishes the page needs to postback, but my function is in
codebehind.

What command do I need to call to say in my finnaly to postback my page???
