Try removing some quotes. According to the jQuery site (http://api.jquery.com/jQuery.ajax/) for .ajax

The data option can contain either a query string of the form key1=value1&key2=value2, or a map of the form {key1: 'value1', key2: 'value2'}.

data: {
  userName:  $("#<%=txtUserName.ClientID%>")[0].value,
  userName1: $("#<%=TextBox1.ClientID%>")[0].value
},
