How I can do that the Enter key have the same effect as the Tab
key in a webform?

You can use a client-side javascript to accomplish this:

function disableEnterKey(){
	if(event.keyCode == 13) 
	   event.keyCode=9 //return the tab key
    event.cancelBubble = true	    
}

then in your html, use the onkeydown="disableEnterKey" as follows:

<input id="whatever" type="text" onkeydown="disableEnterKey()">
