You can read the response from your .Net page e.g.

$(function(){
  $.ajax({
    type: 'POST',
    url: "test.aspx",
    data: "ref=test",
    success: function(r) {  },
    error: function(r) { alert(r.toString()); }
  });
});

You can then read the error message and do the necessary steps..

If you have exception in the Server-Side, then JavaScript couldn't catch the Exception cause JavaScript is in the Client-Side.

You can catch the exception by yourself in Server-Side and send a custom error message to Ajax "success function" to handle the error(Exception) you thrown
