I guess it is due to the page refreshment. Is it clearing automatically or after some operation performed ?

Hey, first of all.. If you are using only the code defined in the article, there is no possibility to get a page postback after a certain while. It is purely a javascript solution. How does it refresh the page automatically if you dont do this manually. If you want to hold data during postback, update a list in the server as well, might be in the session. Call your page using AJAX, may be using a handler / ICallBackEventHandler etc to do this. Another thing, in the javascript, dont use document.all as it is deprecated. Rather use document.getElementById always. var newOption = new Option(); // Create a new instance of ListItem Does this actually works ??? :confused: I would have created an option using document.createElement('option') rather. :rose:
