I'm converting to ASP.NET an ASP project in which each page has its own ControlNumber string, used as a page unique identifier. The whole security model is build around using those ControlNumbers.
On ASP pages ControlNumber are set simply as a constants:
const ControlNumber = "blah-blah"
In ASP.NET I would like to implement a page ControlNumber as persistent BasePage public property, which could be set in VS at design time.
It's easy to inherit BasePage from System.Web.UI.Page, but how to add persistent property, visible in VS at design time?
