Eugh, this is a messy little problem. The error message I get is "Object does not support this set of events," Is that what you're getting?

If so then the reason this is happening is that when a textbox is part of an array it's events have an extra parameter called Index, this is raised as part of their events, your class does not support this version of the event, it only supports the type with no index parameter.

unfortunatley I can't think of a solution to this problem, but I can explain what's happening and maybe someone else will think of one.

sorry
