Module Creation Ascx Page - 'X' is not declared. It may be inaccessible due to its protection level.

On the front end page for an ascx control for a dnn module, I have been including ControlPath, PortalID, PortalSettings.Whatever, etc. on the control front end and have been getting errors from intellisense for years now. Everything works normally when the module is compiled or distributed but Visual Studio intellisense can't find the reference for it. Is there some sort of setting in Visual Studio or some sort of inclusion on the control's ascx that will remove those errors?

Thanks very much!
