Answer 2

A:

<body OnKeyPress="return disableEnterKeyPress(event)">

Here's the javascript function:

<script language="JavaScript">
function disableEnterKeyPress(e)  
{  
 var key;  
 if(window.event)  
      key = window.event.keyCode; //IE  
 else  
      key = e.which; //firefox       

 return (key != 13);  
}
</script>

Update:

I just want to prevent this odd behaviour.(at least odd and unnecessary to me). If I set focus on the textbox and press enter, why was the first button's click button triggered??

This is a bug. At least many people consider it a bug. take a look at the following post:

I think this won't work if a current input is focused, unless he defines the "onkeypress" method inside every input.

Just tested the code. Added a couple of textboxes. tested it when the textboxes are focused and vice versa. It works as expected.
