No problem, dude. The link is working for me, but in case it goes away, Matt's solution is pretty simple: set display:none on the target of the extender: <asp:Panel ID="MyPanel" runat="server" style="display:none"> Depending on your scenario, you may also need to do something similar when OK/Cancel is invoked.
