Thanks.  Along with Mark Waddingham's examples I can see the benefit.

But as for your case, do those newly-created controls get created in a 
stack that ever gets saved?

Call me paranoid (I've been called worse), but with a finite number of 
IDs (2 billion?) when we consider the impact on ID availability of a 
layout that has a couple DataGrids on it, along with other stuff that 
creates thousands of controls, over the life span of a project it seems 
not unthinkable that we might hit the ID limit.

I once tested what happens when the ID limit is hit.  It's not pretty.

Has there been any interest in having that number raised?
