Well, that is because you made the change in UI using Javascript. State was not maintained.

In order to persist it, you need to either keep a flag regarding visibility in a hidden field OR use XMLHttpRequest to save the state of the Panel after making it visible.

For simplicity, use Hidden Fields. At the time of showing the panel, set the value to true. While postback/page re-render, check the value of this hidden field and based on the value set the visibility of the panel.

You should use javascript for this. Here's an example:

Well, you need to write all client side code to do that, obviously. Why would an AJAX call make any difference, it's also going to not cause any postback.

Perhaps if you posted code, we could tell what the issue is ?
