                    ((CustomCheckBox)aChkBoxArray[e.ItemIndex]).bStateChanged = false;
                }

the exception occurs at this line below:

((CustomCheckBox)aChkBoxArray[e.ItemIndex]).bStateChanged = false;

Then I'd guess that e.ItemIndex is either negative, or larger than aChkBoxArray.Length. Neither is good. Debug it.
