I have a master page with a table. The table contains four cells. The top left cell contains a RadPanelBar, the top right cell contains the content, the bottem left cell is empty, and the bottom right cell contains navigation buttons. I have an update panel and a loading panel on the master form. I'm trying to get the loading panel to be semi transparent over the bottom right cell only. The transparency is working, but it covers the entire page. I've attached the master page, and the css for the loading grid.
