| Okay, it turns out it's so simple I missed it: clear the Controls collection, set ChildControlsCreated to false and call
EnsureChildControls(). Although, for some reason, if you clear the Controls collection while ChildControlsCreated is false,
CreateChildControls() gets called automatically on the Clear()...which means it gets called twice. So you have to test the state of
ChildControlsCreated first.
