Attributi

Attributo	Descrizione
defaultColumnWidth	Pubblica. Facoltativa. Il valore predefinito è "20".
displayType	Pubblica. Facoltativa. Il valore predefinito è "String". Specifica il tipo della stringa di visualizzazione. Dopo aver impostato qui, i valori di PROPDESC_DISPLAYTYPE associati vengono recuperati da IPropertyDescription::GetDisplayType. Di seguito sono riportati i tipi validi. Valore Significato string Valore predefinito. Il valore viene visualizzato come stringa. Usare "stringFormat" per formattare. Il metodo restituisce PDDT_STRING. Number Impostazione predefinita per le proprietà numeriche. Il valore viene visualizzato come numero. Utilizzare "numberFormat" per formattare. Il metodo restituisce PDDT_NUMBER. Boolean Impostazione predefinita se <typeInfo type="Boolean">. Il valore viene visualizzato come valore booleano. Usare "booleanFormat" per formattare. Il metodo restituisce PDDT_BOOLEAN. Datetime Valore predefinito se <typeInfo type="DateTime">. Il valore viene visualizzato come data o ora. Usare "dateTimeFormat" per formattare. Il metodo restituisce PDDT_DATETIME. Enumerazione Il valore viene visualizzato come mapping di stringhe di visualizzazione fornito dall'elemento "enumeratedList". Il metodo restituisce PDDT_ENUMERATED.
allineamento	Facoltativa. Il valore predefinito è "Left". Valore Significato Sinistra Valore predefinito. Allinea a sinistra. Center Allinea al centro. Destra Allinea a destra.
relativeDescriptionType	Facoltativa. Il valore predefinito è "General". Specifica come devono essere descritti due valori di questa proprietà quando vengono confrontati tra loro. Nel caso dell'equivalenza, viene sempre usato "Same". IPropertyDescription::GetRelativeDescription e IPropertyDescription::GetRelativeDescriptionType usano questo valore per determinare i nomi visualizzati della descrizione relativa da usare. Valore Significato Generale Valore predefinito. Usa "Different" / "Same" / "Different". Data Valore predefinito se <typeInfo type="DateTime">. Usa "Earlier" / "Same" / "Later" o usa "Older" / "Same" / "Newer" oppure usa "Prima" / "Same" / "Later". Dimensione Usa "Più piccolo" / "Stesso" / "Più grande" Conteggio Usa "Più piccolo" / "Stesso" / "Più grande" Revisione Usa "Earlier" / "Same" / "Later" Length Usa "Shorter" / "Same" / "Longer" Durata Usa "Shorter" / "Same" / "Longer" speed Usa "Più lento" / "Same" / "Più veloce" Tariffa Usa "Più lento" / "Same" / "Più veloce" Classificazione Usa "Lower" / "Same" / "Higher" Priorità Usa "Lower" / "Same" / "Higher"
defaultSortDirection	Specifica la direzione di ordinamento. Il valore predefinito è "Ascending". Valore Significato Crescente Ordina in ordine crescente. Decrescente Ordina in ordine decrescente.
