You can't. Server properties are strictly defined in the control's class and adding your own that the code will not recognize is likely to result in a server error. If you need information on the client you can store it in hidden fields, hidden panels or inject a custom JavaScript object from the server via the ScriptManager.RegisterStartupScript() method.
