Validation in a data entry form
Posted on 2000-05-01
I want to know what is a typical code of validation for a data entry form and in which event I must attach it.
For example I have my form has fields
numeric-integer,real numbers,alphanumeric-string 20 and some of them I want to be required.
Usually I use a DBgrid component for data entry is this right? if not what is better way and which code is necessary.
If is possible to have an example.
