[DUG] Validate data entry

[Colin Johnsun]

Hi John,

Don't have the details in front of me but have a look at TField.OnGetText
event.

Wherever the field gets displayed it will call on its OnGetText event if it
has been defined. In that event you can reformat you field into what ever
string format you like.

Hope this helps,

Colin
