Solução

ajaxToolkit doesn't work very well (I already had a lot of problems with it)! Try on use prettyPhoto:

Outras dicas

Change your css.

 <style type="text/css">
    .modalBackground
    {
        background-color: Gray;
        filter: alpha(opacity=70);
        opacity: 0.7;
    }
    .modalPopup
    {
        background-color: #ffffdd;
        border-width: 3px;
        border-style: solid;
        border-color: Gray;
        padding: 3px;
        width: 250px;
    }
</style>

And set ModalPopupExtender control property BackgroundCssClass="modalBackground". And panel CssClass="modalPopup".

Add the following to your page:

<ajaxToolkit:ToolScriptManager>
etc.

Then put your Panel inside the UpdatePanel
