PublishingPage.ContentType property

Gets the content that is available to this PublishingPage object.

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

public SPContentType ContentType { get; }

Property value

Type: Microsoft.SharePoint.SPContentType
The ContentType property gets the SPContentType for this PublishingPage.

The Layout property that provides rendering information to the PublishingPage matches the ContentTypeproperty(). The PageLayout object supports rendering the pieces of content that are associated with the SPContentType.

The ContentType property value is initialized when you create a PublishingPage; this value is based on the AssociatedContentType and cannot be modified.

The user must have View permissions on the PublishingPage to retrieve it and to return its property values.

This example replaces the PageLayout object for all PublishingPage objects in a Web to a new PageLayout that renders the same type of content.

Before compiling and running this example, verify that the oldPageLayout and newPageLayout render the same content. They should use the same AssociatedContentType value.

using PublishingPage = Microsoft.SharePoint.Publishing.PublishingPage;
using SPListItem = Microsoft.SharePoint.SPListItem;
using SPFile = Microsoft.SharePoint.SPFile;
using SPModerationStatusType = Microsoft.SharePoint.SPModerationStatusType;
using PublishingWeb = Microsoft.SharePoint.Publishing.PublishingWeb;
using SPUser = Microsoft.SharePoint.SPUser;
using PageLayout = Microsoft.SharePoint.Publishing.PageLayout;
using PublishingPageCollection = Microsoft.SharePoint.Publishing.PublishingPageCollection;
