What element Ddl is?

Dropdownlist

DropDownList is a server side control, but you are try to access it on the client...Look into your rendered page on the client. You will not find nothing like DropDownList, but some HTML elements...

Try this:

C#

$(document).ready(function () {
    $('#Ddl').change(function () {
        var $this=$(this).find(":selected");
        var text=$this.text();
        var value=$this.val();
        // do something
    });
});

However, if it is an Asp.Net web form, you need to change the

Dbl

to

<%= Dbl.ClientID %>

due to the dynamic handling of client id by the .net framework.

Everything seems alright to me. I suspect the ID, could you try this

JavaScript

$('#<%= UrDropDownControl.ClientID %>').change(function () {

instead of this line

JavaScript

$('#Ddl').change(function () {

or
Change the line from

JavaScript

Text = $(this).find(":selected").val();

to

JavaScript

Text = $(this).find(":selected").text();
