I have a fairly complex page where i am using a single image css technique for rounded corners. Problem is, if I do not encompass the entire panel with an UpdatePanel, the partial page refresh causes the style to render incorrectly. The reason that this is a problem is because I have buttons that will not work correctly wrapped inside of an update panel. The solution that I found was to set EnablePartialRendering = false. Now, the page does a complete postback with no Ajax like functionality at all which leads me to my question, whats the pont? If I wanted a full postback I would just remove the tags instead.
