My .net 3.5 web application has a gridview inside an update panel. On development machine, all works fine. But when I deployed the application to a Windows 2003 R2 server, the edit/delete buttons in the gridview become inactive. No response on mouse hover, click or any other actions. The gridview gets populated on SelectedIndexChange of a dropdownlist control, which works fine.
IIS 6.0 is used for deployment.
