I am new to ASP.Net and AJAX. I am using the ModalPopupExtender from the AJAX Toolkit 3.5 to show PDF files and that works great. What I would to do is allow the user to resize the popup window and if possible keep it centered on the screen.
Is this even possible? If so, how can I implement it?
I am using Visual Studio 2008 with VB in Code Behind mode.
Any help would be greatly appreciated.
