Introduzione
Una GridBox è un componente non ufficiale ma molto valido per chi lavora spesso con i database. Questo componente, tutto made in Gambas-it.org grazie all'ottimo lavoro dell'utente Milio, permette di creare semplicemente una griglia collegata a un database, con pochissime righe di codice, e già pronta con comandi quali: salvataggio, inserimento, eliminazione, modifica.
Una caratteristica interessante di questo componente è la possibilità di mantenere l'integrità dei dati, con l'aiuto di oggetti quali TextBox, ComboBox, CheckBox, ValueBox, ecc, per una corretta modifica/inserimento di record nel DataBase. Altre caratteristiche sono la formattazione dei dati, mantenendo l'integrità del loro valore, formattazioni condizionate in stile foglio di calcolo, colonne di tipo Formula per facilitare calcoli su i vari record, e altro ancora.
Le Classi esportabili
In questo componente abbiamo i seguenti oggetti che si possono utilizzare:
- GridBox
- Grid
- Conditional
- Cell
Simboli dell'oggetto GridBox
Proprietà
Action
Property Action As String
AlwaysEditable
Property AlwaysEditable As Boolean
Imposta la griglia in modo che le celle siano sempre editabili. Usando il Tab o le frecce, il focus verrà spostato solo sulle celle che hanno la proprietà ReadOnly impostata a False.
AutoDataType
Property AutoDataType As Boolean
Imposta in automatico la proprietà DataType delle colonne di tipo Field in base al tipo di dato passatogli dal metodo LoadData.
AutoNew
Property AutoNew As Boolean
Questa proprietà, legata alla proprietà AlwaysEditable, fa in modo che, spostandosi dall'ultima cella editabile dell'ultima riga della griglia, crei in automatico una nuova riga per l'inserimento di un nuovo record.
