i want to display the pop ups in asp.net page like how the stack over flow show the pop ups on the top of the site (you get the new answer for the question like that in a orange color) how can i write the code is there any free source code or any reference. thank you
That is not a 'popup', it is probably just a standard DIV that has its height and content changed dynamically. You can do a "view source" on the page to locate the item, or use Firebug (easier).
After looking, it is a div called 'notify-container'.
