The content class is a high level object model for representing content repository content. It provides high level data manipulation features like field data accessing and field validation, provides a generalized interface to be used on the UI and wraps a node object which provides basic storage-related features.


Loading content

There are two ways to load content from the content repository with the content API. The easiest is to use the Load function:

var content = Content.Load("/Root/Sites/Default_Site/myContent");

If the specified content does not exist Content.Load will return with null.

You can also create the content wrapper over a node object:

var node = Node.LoadNode("/Root/Sites/Default_Site/myContent");
var content = Content.Create(node);

Operations with content

Modifying field data

You can use an indexer to access field data:

var content = Content.Load("/Root/IMS/Builtin/Portal/Admin");
content["Email"] = "";

Please note that in an enterprise environment you need to take concurrency into account when saving content.

It is also possible to access fields and use the retrieved field object to manipulate data:

var content = Content.Load("/Root/IMS/Builtin/Portal/Admin");

Copying, moving

Copying and moving is not available from the content API. Use the underlying content handler for these operations:

var content = Content.Load("/Root/Sites/Default_Site/myContent");
var target = Node.LoadNode("/Root/Sites/Default_Site/myFolder");


To delete a content using the content API use the following syntax:

var content = Content.Load("/Root/Sites/Default_Site/myContent");

To move to trash instead of permanently delete the content use the following overload:


Versioning and approval

For versioned saving of a content you can use the following functions:

content.CheckOut(); // checks out the content to the current user
content.UndoCheckOut(); // undos changes by the current user
content.ForceUndoCheckOut(); // undos changes made by another user
content.CheckIn(); // checks in the content
content.Publish(); // publishes the content (only in major&minor versioning)
content.Approve(); // approves the content
content.Reject(); // rejects the content

Calling content.Save() will save the content in the appropriate version according to the versioning of the content. You can use the SaveSameVersion in order to save changes on the current version:

// versioning: none
content.Save(); // from 1.0A to 1.0A
content.SaveSameVersion(); // from 1.0A to 1.0A
// versioning: major
content.Save(); // from 1.0A to 2.0A
content.SaveSameVersion(); // from 1.0A to 1.0A
// versioning: major and minor
content.Save(); // from 1.0A to 1.1D, from 1.1D to 1.2D, etc..
content.SaveSameVersion(); // from 1.0A to 1.0A, from 1.1D to 1.1D, etc..

Calling content.Save() on a locked content will always save on the current version:

// content.ContentHandler.Locked == true
content.Save(); // from 2.0L to 2.0L, from 1.1L to 1.1L, etc..

There are also some helper properties to determine the current state of the content:

content.Approvable; // true if content is approvable
content.Publishable; // true if content is publishable
content.IsLatestVersion; // true if content object corresponds to the latest version
content.IsLastPublicVersion; // true if content object corresponds to the last public version

Creating content

To create a new content using the content API, use the following syntax:

var content = Content.CreateNew("Car", parent, "MyCar");

It is also possible to create a node using the node API or content handler and create the content wrapper afterwards:

var parent = Node.LoadNode("/Root/IMS/Builtin/Portal");
var user = new User(parent);
var content = Content.Create(user);

Content and the UI

Content is the general object model for UI-related functions. For example you need a content object to create a contentview and visualize it on a page (eg.: in a portlet):

var content = Content.Load("/Root/Sites/Default_Site/myList/myContent");
var contentview = ContentView.Create(content, this.Page, ViewMode.InlineEdit);

You can also reach the visualized content from the markup of a contentview:

<%= this.Content["Email"] %>


<%=GetValue("Email") %>

Content and node

Content is a high-level object model wrapping the low-level storage model node. The wrapped node object is always accessible from the content interface:

var underlyingnode = content.ContentHandler;

To learn more about the low-level object and its capabilities, read the following article:
