Please help with using constraint

[jeud]

I'm using Delphi 7 and like to migrate from BDE to uniDAC.

I'm trying to setup constraint on TField level, it's used to work on BDE, this is what I have done. Also uniDAC is using standard Delphi's TField descendants I have no ideas what went wrong.

Code: Select all

UniQuery1gender: TStringField;

UniQuery1gender.CustomConstraint := 'x in (''M'',''F'')';
UniQuery1gender.ConstraintErrorMessage := 'Gender must be M/F only';

When the program is running nothing happen, the program is still accept invalid input.

Please help.
Thanks.

Hello,

Unfortunately, now UniDAC doesn't have such features.
We will investigate the possibility of adding such features in one of the next builds/versions.
