Hi
You should have somePlaceHolder for adding element into the html through javascript so that when you do the page doesnot get refresh like div or span
<div id="div1"></div>
add the onClick event on your so called add button which will then call some javascript method
In this javaScript method now you can add
function showSomeThing(){
var divName =document.getElementById("div1");
divName.innerHTML="<input type='file' name='FileName'/>";
}
and on your server side code you can access this fileName using someName as parameter name, sent from the client.
