How to implement Undo and redo operations in .NET

Bradley, Peter
What do you want to undo and redo? An ASP.NET page? A Windows form? A single control in a Web page? A single control in a form? Groups of controls? What types of controls (e.g. do you want word-by-word undo/redo in a text control)?

I am writing an windows application in C#.NET. What I am trying
to do is I am creating some graphical shapes on the form. let us assume
that I draw a sqaure, a rectangle , a line on the form in the same
order.
So when I click Undo, at first line has to be disappear. Next
when I click undo , rectangle has to disappear.
In short , I need something where all the user actions can be
saved and then retreive it when desired . I know that we can use stack
and arraylist for this. But I am in need of some more information on
this.
Thanks,
Yesh
