Hello, Assigning OnGetText event of TField doesn't make any difference if field is in TreeKeyFields for TUniDBTreeGrid . In TuniDBGrid it shows correct, but in TUniDBTreeGrid it shows original value. Issue: TDataSet/Query has fields: SEQ_1, SEQ_2, SEQ_3, PRODLEV1, PRODLEV2, PRODLEV3, Field_Name Field_Value When I assigned TreeKeyFields := 'PRODLEV1; PRODLEV2;PRODLEV3'; The first node come ARC and not EME, so it alphabetical order and not as order in TDataSet. I found your comment that it could be used OnGetText to change text for nodes in TUniDBTreeGrid, I have changed TreeKeyFields from 'PRODLEV1; PRODLEV2;PRODLEV3' to TreeKeyFields := 'SEQ_1;SEQ_2;SEQ_3'; And plus to that I have created OnGetText for SEQ_1,SEQ_2,SEQ_3 fields to show Text and not Sequence number, but it shows sequences: 1, 2, ... and not EME, ARC, ..... for nodes in the DBTreeGrid. You can see in attached image TUniDBGrid shows values based on OnGetText correctly, but TUniDBTreeGrid does not. I have attached two images: one is screen from app and other some data example, so you can have some idea about data. What I try to achieve is make DBTreeGrid to show data in order based on SEQ_1, SEQ_2, SEQ_3 and not in Alphabetical order. I am working on the latest full license, WebApp is desktop. Could you please suggest any solutions? Thank you in advance. Kind Regards.
