>Are you sure that the textbox is bound to a date field? It seem to me that it is a datetime field. If that is the case, you will need to unbound the textbox from the field and update this control manually or change the field to type date.

You're right, it is a datetime field. Time as part of this entry is important but not seconds. I would like to keep it bound if possible because it does some automatic date verification. Is there no way to format a datetime fiels?
