  You can use "onchange" event in JS..check this.. 

  DropDownList1.Attributes.Add("onchange", "getIndex();") ;// where getIndex is JS function

  how do I retreive which value was selected?

   

  var e = document.getElementById("DropDownList1"); //If it doesn't work, use clintID
  var str = e.options[e.selectedIndex].value;
