ASP.NET Page inheritance and controls

Hi,
I have ASP.NET Page - PageBase and some pages that inherits this page:
public class PageBase : System.Web.Page
public class SomePage : PageBase
I would like to have some controls placed in PageBase that every page that inherits from this page (like SomePage example) will have it displayed as well.
This works perfectly in WinForms. If I place control (in designer mode) to WinForm A, I will get it displayed in form B - that inherits from A.
This is perfect for building complex solution and I need to extend my WinForm solution to web.


How will I do it in ASP.NET?


Thank you for any advice!
