I have a draggable a panel with a ModalPopupExtender with an UpdatePanel inside it. Whenever I have an asynchronous postback run, the popup "jumps" back to to the center of the screen. Ideally it would stay in whatever position it is currently in, as the jump is jarring to the user experience.
Anyone know a way to avoid this?
Thanks!
Hi MWB,
To troubleshoot this issue, we really need the source code to reproduce the problem, so that we can investigate the issue in house. It is not necessary that you send out the complete source of your project. We just need a simplest sample to reproduce the problem. You can remove any confidential information or business logic from it.
Best regards,
Jonathan
Hi Jonathan -
Thanks very much for responding. I put together an extremely simple (and rather ugly, so forgive me) website project that reproduces the jumping modal popup behavior. Please let me know if you have any thoughts or questions. Since I can't directly upload the project files, the code is below.
Thanks again!

<p>How to reproduce the jumping Modal Popup issue:</p>
<ol>
<li>
Drag the popup using the blue box that says "Drag Me" above
so that the popup is no longer in the default centered location

<li>Click "Generate Asynchronous Postback"</li>
<li>
Note how the popup "jumps" back to the default

Hi MWB,
Thanks for your sample.I have reproduced your problem with your sample.
Based on my research and testing, I'm afraid that what your want is not achievable in your case.It will automaticlly reset to orignal position when a post occured.Thanks.
Best regards,
Jonathan
