Esempio

L'esempio di codice seguente crea due DataGridTableStyle oggetti e aggiunge ognuno all'oggetto GridTableStylesCollectionTableStyles restituito dalla proprietà di un DataGrid controllo.

Commenti

Contiene GridTableStylesCollectionDataGridTableStyle oggetti che consentono al DataGrid controllo di visualizzare uno stile di griglia personalizzato per ognuno DataTable in un DataSetoggetto .

DataGrid Nel controllo la TableStyles proprietà restituisce .GridTableStylesCollection

Per impostazione predefinita, l'oggetto GridTableStylesCollection non contiene DataGridTableStyle oggetti. Visualizza invece DataGrid ogni tabella usando le impostazioni predefinite per colore, larghezza e formattazione. Vengono visualizzate tutte le colonne di ogni tabella. Quando un oggetto DataGridTableStyle viene aggiunto all'insieme, usa l'oggetto DataGridMappingName per determinare quali oggetti forniscono i dati per la griglia. Ad esempio, se l'origine dati è un oggetto DataSet contenente tre DataTable oggetti, deve MappingName corrispondere a TableName uno degli oggetti. Se non MappingName corrisponde a nessuno dei TableName valori, le impostazioni predefinite verranno usate per visualizzare i dati per ogni tabella e le DataGridTableStyle impostazioni verranno ignorate.
