- Aggregation example on 2 lines
Procedure TForm1.dxDBGridControler1Aggregation(Sender: TdxDBGridControler);
Begin
Sender.ColumnPropertyList.ColumnPropertyByName('ProjectManager').FooterAlignment := taRightJustify;
Sender.ColumnPropertyList.ColumnPropertyByName('ProjectManager').FooterDisplayText :=
'Count Distinct : ' + Sender.ColumnPropertyList.Aggregation(agDistinct, 'ProjectManager').AsString;
// Use the FooterPanel property to set the height : dxDBGridControler1.FooterPanel.Height := Self.DBGrid1.DefaultRowHeight * 2;
Sender.ColumnPropertyList.ColumnPropertyByName('OpeningDate').FooterAlignment := taCenter;
Sender.ColumnPropertyList.ColumnPropertyByName('OpeningDate').FooterDisplayText :=
'Min : ' + Sender.ColumnPropertyList.Aggregation(agMin, 'OpeningDate').AsString + Char(13) + Char(10) +
'Max : ' + Sender.ColumnPropertyList.Aggregation(agMax, 'OpeningDate').AsString;
End;
- Localization example, french translation of some of the component string resources
Procedure TForm1.dxDBGridControler1Localize(Sender: TObject; Component: TComponent; ID_Ressource: String; Var Translation: String);
Begin
If ID_Ressource = msg_search Then
Translation := 'Recherche...'
Else If ID_Ressource = msg_first Then
Translation := 'Aller au début'
Else If ID_Ressource = msg_prior Then
Translation := 'Précédent'
Else If ID_Ressource = msg_next Then
Translation := 'Suivant'
Else If ID_Ressource = msg_last Then
Translation := 'Aller à la fin'
Else If ID_Ressource = msg_add Then
Translation := 'Ajouter'
Else If ID_Ressource = msg_delete Then
Translation := 'Détruire'
Else If ID_Ressource = msg_edit Then
Translation := 'Éditer'
Else If ID_Ressource = msg_save Then
Translation := 'Enregistrer'
Else If ID_Ressource = msg_cancel Then
Translation := 'Annuler'
Else If ID_Ressource = msg_refresh Then
Translation := 'Actualiser'
Else If ID_Ressource = msg_btncancel Then
Translation := 'Annuler'
Else If ID_Ressource = msg_of Then
Translation := 'de'
Else If ID_Ressource = msg_nodata Then
Translation := 'Aucune donnée trouvée!';
