    Hello Galina,

    Please, open the web.config file and look for this line:

    <xhtmlConformance mode="Legacy"/>

    The xhtmlConformance element is usually added when an application is migrated from VS 2003 and unfortunately it is not compatible with the ASP.NET AJAX extensions (see Remove it and see if the dialogs problem is fixed.

    All the best,
