First blog entry for March 2009!
Mark this one as problem solved.
I am working on a project that uses ASP.NET Master Pages. I added an Ajax ModalPopupExtender to a Content page, but it was not rendering properly.
The modal panel was displaying at one location, not at the center of the page, and the shadow was displaying somewhere else. I discovered that the following DOCTYPE declaration was missing from the Master page.
<!
DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
Now the modal is displaying properly.
