Hinweise
Verwenden Sie diese Eigenschaft, um einen benutzerdefinierten Stil für den Pagingabschnitt des DataGrid Steuerelements bereitzustellen. Zu den allgemeinen Formatattributen, die angepasst werden können, gehören forecolor, backcolor, font und content alignment innerhalb der Zelle. Das Bereitstellen eines anderen Stils verbessert die Darstellung des DataGrid Steuerelements.
Um einen benutzerdefinierten Stil für den Pagingabschnitt anzugeben, platzieren Sie die <PagerStyle>
Tags zwischen den öffnenden und schließenden Tags des DataGrid Steuerelements. Anschließend können Sie die Formatattribute innerhalb des öffnenden <PagerStyle>
Tags auflisten.
