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?
