how do i get the id of a parent (country) dropdown element?

"country" is not a "parent" in the HTML above, it's simply another element. The above code, but replacing `#state` with `#country` would get what you want. Or am I misunderstanding? Do you want the "previous" element instead?

under which <select> is the element that you are currently in? IF you're in an element under the state select, then you would simply do: $("#country").val();

i have append the latest code, please have a look at it. - thanks.

by populating the dropdown using ajax, it's selected value is not getting saved in the viewstate. Perhaps you could pass the selected value in the querystring on postback so you can re-select the value on page load.
