Script controls may not be registered after PreRender in Beta

[MGrassman]

I am recieving the following error when I upgrade past version v.21010.1.216.35.  I have tried this with v.2010.1.519.35 and v.2010.2.623.35.

The page loads fine with the 216 but when I upgrade to a newer version I recieve "Script controls may not be registered after PreRender"  My app doesn't change I just use the telerik upgrade option in the file menu.

        [WebMethod]
        public static void MarkRecordDeleted(int RecId)
        {
            Guid? userGuid = UserUtil.getCurrentUserGuid(Membership.GetUser());

            ContactEntity ent = new ContactEntity(RecId);
            ent.DeletedBy = userGuid;
            ent.DeletedDate = DateTime.Now;
            ent.Save();
        }

This is the only page it happens on.  I don't see where I'm adding a control after PreRender either?

Thanks,

Hello MGrassman,

I examined your code but I am not able to find anything peculiar in the implementation which might cause this exception to appear. To progress in our investigation, I would offer you to isolate a stripped working version of your project and send it enclosed to a regular support ticket. We will debug it locally and will get back to you with our findings.

You may also perform a quick test replacing the LLBLGenProDataSource controls with asp ObjectDataSources temporary to see whether this makes a difference (although I doubt that the data sources may be the cause of the issue here).

Kind regards,
Sebastian
