I have occasions when a user changes the entry in one control the entry in
another control is automatically changed.

I have got into a muddle and I am not sure if I should be changing the value
of the second control, or the field in the underlying record that the
control is bound to. I want to do this in such a way that the CancelEdit
feature works.

As a specific example I am using the CheckedChanged event of a check box to
clear the data in another field if the check box is cleared.


many thanks in advance
