Ah, I didn't understand that. I guess as you have seen using the Got/LostFocus won't really work, however you could probably get it to work in another way.

If you add some properties like:

EncryptDecryptThis logical
FieldToEncrypt character

don't bind the control to a field.

then in the refresh of the control call the decrypt code and set the control's value to the decrypted text and in the lostfocus of the control call the encrypt code and then manually set the field to the encrypted value.

That's off the top of my head, but should set you on the right path.
