The original problem in this thread is already fixed. Most of our controls are Naming Containers and expect their child controls to have certain IDs. We modified the base control classes (RadWebControl, RadDataBoundControl, etc.) and overrode the ClientIdMode property there (set it to AutoId)) and now everything works fine.
In case that you have some styling issue, please open a new support thread and send us a runnable demo project where we can observe the issue. Once we receive it, we will do our best to help.
