The PageData
class contains content and meta data about a specific page. This includes the
name of the page (Name), reference (
PageData
is in many respects synonymous with the web page that it is holding properties
for. One example of this is the Changed property, which holds last date and time
the PageData object, in other words the web page, was changed.
Constructors
PageData()
Creates an empty PageData object.
Declaration
public PageData()
PageData(PageData)
Constructor that creates a new instance by shallow copying the state from another instance.
Declaration
public PageData(PageData copy)
Parameters
Type | Name | Description |
---|---|---|
PageData | copy |
PageData(PageReference)
Creates an empty PageData object for the given PageReference.
Declaration
public PageData(PageReference pageLink)
Parameters
Type | Name | Description |
---|---|---|
PageReference | pageLink | The PageReference for this page. |
PageData(AccessControlList, PropertyDataCollection)
Creates an empty PageData object for the given AccessControlList and PropertyDataCollection.
Declaration
public PageData(AccessControlList acl, PropertyDataCollection coll)
Parameters
Type | Name | Description |
---|---|---|
AccessControlList | acl | Access control list |
PropertyDataCollection | coll | Property data collection |
Properties
ACL
Gets the list of access permissions of this page. This AccessControlList describes what access certain users and roles has to this page.
Declaration
public virtual AccessControlList ACL { get; set; }
Property Value
Type | Description |
---|---|
AccessControlList |
Remarks
ACL holds the Access Control List for a PageData object. Since PageData has the attribute Property which is a PropertyDataCollection, ACL effectively controls access to the web page. Keep in mind that the Access Control List applies to all of the PageData object and its attributes. It is not possible to have different access permissions for different properties.
The Acccess Control List is comprised of an Access Control Entry, ACE, array and is accessed by calling the method ACL.ToRawACEArray.
Examples
The following code example demonstrates the usage of ToRawACEArray to enumerate the Access Control Entries. The example enumerates the RawACE objects, which together form the Access Control List and check if one of them is the Create permission.
foreach ( EPiServer.Security.RawACE Ace in CurrentPage.ACL.ToRawACEArray() )
{
if ( ( Ace.Access & EPiServer.Security.AccessLevel.Create ) == EPiServer.Security.AccessLevel.Create )
{
// Do something
}
}
The following code example demonstrates the usage of QueryDistinctAccess to check specific access for the current user.
if ( CurrentPage.ACL.QueryDistinctAccess( EPiServer.Security.AccessLevel.Create ) )
{
// Checks whether the currently logged-on user has
// create permission for the current page.
}

PageLink
Gets or sets the unique PageReference identifier of the current page.
Declaration
public virtual PageReference PageLink { get; set; }
Property Value
Type | Description |
---|---|
PageReference |
Remarks
The use of PageLink is derived from the way in which EPiServer is structured. Pages are nothing more than an instance of an EPiServer page type and a collection of property settings stored in the database. Individual pages are identified by the pkID column in the database table tblPage and transforming this into a URL, you get something looking like "templates/emailpagecontainer.aspx?id=n?", where "n" is the previously mentioned pkID and thus the unique page identifier.
Examples
The following example demonstrates the usage of PageLink in HTML.
As PageLink is guaranteed to be unique among all pages in a certain EPiServer instances, it is used in the following example to create unique IDs and names for HTML check boxes. The code is used to present the visitor with a selection of pages and allows them to select one or more for further processing.
<EPiServer:PageList SortBy="PageName" DataSource="<%#PropertySearchControl%>" runat="server" ID="PageListControl">
<ItemTemplate>
...
<input type="checkbox" id="ViewUser<%#Container.CurrentPage.PageLink%>" name="ViewUser<%# Container.CurrentPage.PageLink %>" />
...
</ItemTemplate>
</EPiServer:PageList>
PageName
Gets or sets the display name of page.
Declaration
public virtual string PageName { get; set; }
Property Value
Type | Description |
---|---|
System.String |
Remarks
Not many page settings are under absolute editor control, but PageName is one of them. PageName is a descriptive name given the page in Edit mode. PageName can be used to great benefit in many cases, such as templated controls.
Examples
The following example demonstrates the usage of PageName and LinkURL. The HTML code below produces two HTML table rows for every news item page displayed. The first row displays the content of the property PageStartPublish and the second row is an HTML anchor tag, where PageData.LinkURL is the relative URL for the page and PageData.PageName is used as a new headline. Note that PageData.Item is used twice in this HTML code, as the two attributes PageStartPublish and MainIntro are accessed using the indexer for the PageData property.
<EPiServer:Newslist ID="Newslistnew" Pagelinkproperty="NewsContainer" runat="server" MaxCount='<%# GetNewsCount() %>'>
<NewsTemplate>
<tr>
<td class="DateListingText"><%# Container.CurrentPage[ "PageStartPublish" ] %></td>
</tr>
<tr>
<td>
<a href="<%# Container.CurrentPage.LinkURL %>" class="StartPageHeading">
<%# Container.CurrentPage.PageName %></a> <br />
<span class="Normal">
<%# Container.CurrentPage[ "MainIntro" ] %>
</span>
</td>
</tr>
</NewsTemplate>
</EPiServer:Newslist>
PageTypeName
Gets or sets the name of the PageType used to create this page.
Declaration
public virtual string PageTypeName { get; set; }
Property Value
Type | Description |
---|---|
System.String | A string with the name. |
Remarks
This is the page type name as entered in Admin mode. It will not be translated in any way. PageTypeName is the same as column Name in the database table tblPageType.
ParentLink
Gets or sets a reference to the page that is the closest parent of this page.
Declaration
public virtual PageReference ParentLink { get; set; }
Property Value
Type | Description |
---|---|
PageReference |
Remarks
Parent and childhood is determined by placement in the page tree.
Examples
In the following code example ParentLink is used twice. First make sure it contains a non-empty PageReference and secondly to retrieve the sibling of the current page.
if ( CurrentPage.ParentLink != EPiServer.Core.PageReference.EmptyReference )
{
EPiServer.Core.PageDataCollection siblings = GetChildren( CurrentPage.ParentLink );
}
The following code example demonstrates the usage of ParentLink. The example results in the name of the parent page being displayed.
Parent Page Name: <%= GetPage( CurrentPage.ParentLink ).PageName %>

Methods
CheckPublishedStatus(PagePublishedStatus)
Indicates whether the page should be displayed based on publish date.
Declaration
public bool CheckPublishedStatus(PagePublishedStatus status)
Parameters
Type | Name | Description |
---|---|---|
PagePublishedStatus | status | The type of publish status to check against. |
Returns
Type | Description |
---|---|
System.Boolean | True if the page should be displayed. |
Remarks
Used internally to filter pages in listings. You should usually not need to refer to this method directly.
Copy()
Creates a deep copy of the current object, as opposed to a shallow copy.
Declaration
public PageData Copy()
Returns
Type | Description |
---|---|
PageData | A new PageData. |
Remarks
In most cases you will probably want to use the new CreateWritableClone() method instead, since copying a read-only instance will return a new read-only instance.
This method performs a deep copy and the copy should therefore have no references to the original PageData instance. This is to say that you can freely modify the copy without altering the original.
CreateWritableClone()
Creates a writable clone of this object.
Declaration
public PageData CreateWritableClone()
Returns
Type | Description |
---|---|
PageData | A writable PageData object. |
CreateWriteableCloneImplementation()
Creates a writable clone of this object.
Declaration
protected override object CreateWriteableCloneImplementation()
Returns
Type | Description |
---|---|
System.Object | A clone of this object that is writable. |
Overrides
Remarks
This method is called by CreateWritableClone(). If you are inheriting, directly or indirectly, from ContentData you should override this method to make sure that all reference type members of your class are cloned.
Your override of this method must create the clone by calling base.CreateWritableCloneImplementation()
. This ensures that all
classes in the inheritance chain can create clones as necessary. Also, by calling the base implementation the values of all value
type members are copied as the ContentData implementation of this method calls System.Object.MemberwiseClone().
GetContentSecurityDescriptor()
Gets the security descriptor.
Declaration
public virtual IContentSecurityDescriptor GetContentSecurityDescriptor()
Returns
Type | Description |
---|---|
IContentSecurityDescriptor | An implementation of ISecurityDescriptor. |
