Kommentarer
Använd egenskapen PagerSettings för att styra inställningarna för pager-raden i en DetailsView kontroll. Personsökarraden visas när växlingsfunktionen är aktiverad (genom att ställa in AllowPaging egenskapen på true) och innehåller de kontroller som gör att användaren kan navigera till de olika posterna i kontrollen. Den här egenskapen är skrivskyddad. Du kan dock ange egenskaperna för det objekt som PagerSettings returneras. Egenskaperna kan anges deklarativt i formuläret Property-Subproperty, där Subproperty är en egenskap PagerSettings för objektet (till exempel PagerSetting-Mode). Egenskaperna kan också anges programmatiskt i formuläret Property.Subproperty (till exempel PagerSetting.Mode). Vanliga inställningar är vanligtvis sidradens visningsläge och anpassad text eller bilder för navigeringskontrollerna.
