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)

Syntax

'Declaration
Public Sub New ( _
    listItem As SPListItem _
)
'Usage
Dim listItem As SPListItem

Dim instance As New PageLayout(listItem)

public PageLayout(
    SPListItem listItem
)

Parameters

• listItem
  Type: Microsoft.SharePoint.SPListItem

  The SPListItem object that is constructed.

Exceptions

Exception	Condition
ArgumentNullException	The listItem is a null reference (Nothing in Visual Basic), which is not valid.

Remarks

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).

Examples

Before compiling and running this example, verify that the SPListItem object is a list item for a page layout that resides in the master page gallery on the top-level Web site.

This example assumes that the master page gallery that contains the SPListItem object requires content approval.
