Question

I have an input box that I don’t want postback to occur on someone striking the enter key

I want the javascript event to take place instead.

<input 
type="text" 
id="addressInput" 
onkeydown="inputenter()" 
autopostback="false"/>

    function inputenter() {
        if (event.keyCode == 13) {
            seachLocations();
            return false;
        }
        else {
            return false;
        }
    }

<input type="text" id="addressInput" onkeydown="if (window.event.keyCode == 13) 
{
    event.returnValue=false; 
    event.cancel = true;
    searchLocations();
}" />
