I have 5 radbuttons on a page. Initially the radbuttons display just fine. The buttons are all within a RadAjaxPanel. The function of one of the buttons is to update a RadGrid on the page. When this button is clicked, the RadGrid updates correctly, but all five buttons on the page disappear. I am using IE8 and the behavior only happens when I am running in compatibilty mode. Some users for this project may use IE6 or IE7. Any help will be appreciated.
