Why don't you use rad Ajax and AjaxPanel - this way, you can easily change the visibility of any control - just make sure it is embedded inside ASP:Panel, as described in this online help topic:
The visibility of controls is best controlled during the ajax request if they are placed inside a control on the page that is always visible. Here are the exact steps:
1. Place the control in an element which is always visible, such as a Panel, an AJAX Panel or a DIV. 2. Add this visible control to the AJAX pairs where the AJAX initiator control should update the visible control. 3. Change the Visible property of the control you want to hide/show.
