Use Kelsey's Answer (This answer is wiki'ed)

...but please note a few things when you implement it.

1. I'd recommend the plain old javascript method if you're not already using jQuery. if you do that method, just return (keynum != 13) don't do something silly like if(true) return true; else return false;

2. You don't have to assign onkeydown from the code behind. That can be done in the markup and it's a lot cleaner when you do.

3. Don't disable the enter key in your entire form. You can do it in your inputs only, but if you do it in the entire form you won't be able to add a carriage return in a textarea.

4. If you do use jQuery, I'd recommend adding a CSS class called "disableEnterKey" and assigning it to your form elements you want to disable, then calling Kelsey's jQuery method on $(".disableEnterKey") in the document ready.

5. Don't answer too similar to anyone on SO, even if you don't fully agree with the answer. And even if the answer was simple and thousands of people probably have done the samething. It's "copying". Which is similar to being a "cutter" or a "tattle tale"... which is bad.
