I have an Asp.Net page that I am using on an iPad. The page uses the modalPopUpExtender on a button click. I am using AJAX Control Toolkit for .Net 3.5. The modal panel displays, but it is always at the top of the screen instead of in the center of the display. So on long pages, if the users clicks a button on the bottom of the page, they need to scroll back up to the top to interact with the panel. Does anyone know a solution to this issue? Thanks in advance.
