Tab order is changing on partial postback

I have three dropdown list on my page for country, state, city, area and society. All these 5 dropdown list are in update panel so that I can use partial rendering features of AJAX. Its working fine. All 5 dropdown list are working great and I was feeling proud that I implemented it.

But fuck to my tester who find out issue related with these dropdown list as well. Whenever he select state, my tab order is changed and instead of state itself, my default focus set to next control after society. However in any situation it should focus on current dropdown list.

I tried to solve it though javascript and JQuery but none of them work.

To solve this just write below code in current postback event as

        protected void ddlState_SelectedIndexChanged(object sender, EventArgs e)
            DropDownList ddlList = (DropDownList)sender;

Please leave your comments or share this code if it’s useful for you.
