Artikel
03/15/2016

Ermöglicht das Hinzufügen von PortalSiteMapNode -Objekten unter ein PortalWebSiteMapNode -Objekt.

Namespace: Microsoft.SharePoint.Publishing.Navigation
Assembly: Microsoft.SharePoint.Publishing (in Microsoft.SharePoint.Publishing.dll)

Syntax

'Declaration
Public Overridable Function CreateAdditionalSiteMapNodes ( _
    webNode As PortalWebSiteMapNode _
) As SiteMapNodeCollection
'Usage
Dim instance As PortalSiteMapProvider
Dim webNode As PortalWebSiteMapNode
Dim returnValue As SiteMapNodeCollection

returnValue = instance.CreateAdditionalSiteMapNodes(webNode)

public virtual SiteMapNodeCollection CreateAdditionalSiteMapNodes(
    PortalWebSiteMapNode webNode
)

Parameter

webNode
Typ: Microsoft.SharePoint.Publishing.Navigation.PortalWebSiteMapNode

Ein PortalWebSiteMapNode -Objekt, das einen bestimmten Webserver in der Navigationsstruktur darstellt.

Rückgabewert

Typ: System.Web.SiteMapNodeCollection
Ein PortalSiteMapNodeCollection -Objekt, fügen Sie unterhalb der übergebenen Knoten Web-Knoten darstellt.

Hinweise

Diese Methode wird aufgerufen, nachdem die untergeordneten Objekte eines Objekts PortalWebSiteMapNode auffüllen.

Ruft beim Überschreiben in einer abgeleiteten Klasse können Sie eine benutzerdefinierte PortalSiteMapNode -Objekt oder ein Objekt abgeleitet aus einem PortalSiteMapNode -Objekt unter dem angegebenen Web-Knoten im Navigationsbereich hinzufügen.
