PageLayout Constructor

Uses the SPListItem class to construct a PageLayout list item object in a document library.

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

public PageLayout(
	SPListItem listItem
)

Parameters

listItem
Type: Microsoft.SharePoint.SPListItem
The SPListItem object that is constructed.

ExceptionCondition
ArgumentNullException

The listItem is a null reference (Nothing in Visual Basic), which is invalid.

Use this method to instantiate a PageLayout instance that wraps an SPListItem object that you have already retrieved. The SPListItem should be an item in the Master Page Gallery of the site collection.

The listItem must be an SPListItem instance and cannot be a null reference (Nothing in Visual Basic).

Before compiling and running this sample, verify that the SPListItem object is a list item for a page layout that resides in the Master Page Gallery on the root Web site.

This sample assumes that the Master Page Gallery that contains the SPListItem object requires content approval.
